pcb-rnd 3.0.4 (r36160)
~~~~~~~~~~~~~~~~~~~~~~
	[core]
		-Change: disable auto_via by default, there are too many corner cases lurking
		-Fix: find.c poly-poly isc: when conveting contour lines to polygons, use square cap so tiny round caps are not generated (they are prone to self-intersect in this range)
		-Fix: pixmap rendering: calculate rotation not from the input forward, but from the output back to get every pixel filled in
		-Fix: ChkLayer() invalid layer ID error message printed the wrong layer name field
		-Fix: verify that emergency file name template contains at most one %ld and no other format string
		-Fix: "polygon cleared out of existnece" error message uses current grid units, not mm hardwired for reporting bbox center
		-Fix: make sure all internal parameters of buffer operations are initialized
		-Cleanup: file_act's action list should be static as it is local (namespace pollution)
		-Cleanup: use matrix transformation instead of manual cos/sin in pixmap rotation
		-Add: hint on what the user could do on "poly cleared out of exitence" warning
		-Add: "poly cleared out of existence" error message also prints layer name

		-Fix: don't let thermal scale go above 1.5, to avoid self-intersecting polygons
		-Fix: preferences: board name change should trigger the appropriate name change event so that the title is updated
		-Fix: padstack proto lib: 'new' button: save don't let tree update change the target ID we are going to edit
		-Fix: padstack proto lib: refresh the tree after padstack edit, because the name of the edited padstack may have changed
		-Cleanup: preferences dialog: remove dependcy on global PCB

	[doc]
		-Fix: installation: pcb-rnd is not compiled with or without gui, it merely runs with or without gui

		-Add: document how to work around OSX library path block
		-Update: new version of manmarkup is in fawkml

	[export_gerber]
		-Fix: allocate empty-layer dummy aperture instead of hardwiring aperutre 11 - in cam export this results in duplicate apertures

	[extedit]
		-Fix: make sure a subc is picked for extedit, refuse to use any other object type or no-object

	[fontmode]
		-Fix: when packign arc for font save, use arc bbox center instead of arc center point; if the arc has a large radius and a small delta, e.g. it's a "parenthesis", the center point falls into a different font cell than the actual graphics of the arc (always consider the graphics, not the invisible arc center)
		-Fix: char width calculation should use arc naked bbox X2 instead of cx because of "small delta, big radius" arcs
		-Fix: when packing arcs on save, use arc center for new arc center, compensated with ox and oy, instead of bbox center
		-Fix: clear all content of symbols before rendering them again for a save

	[footprint]
		-Fix: remove bga() stale debug printout
		-Fix: bga: when both nx;ny and map are specified, take the larger and do not add 1 row/col (fixes the bug of excess row/col when both specified)

	[io_dsn]
		-Fix: ses import: expect via name as pstk_ID instead of the old via_dia_dia description

	[lib_hid_pcbui]
		-Fix: refresh window title after save as (file name change)
		-Fix: typo: wrong number of conf paths for infobar watch

		-Fix: advanced search dialog: when filling strings back in the dialog on a subsequent edit, remove double quotes required by the syntax but not required in the GUI
		-Fix: advanced search dialog: don't crash on empty string on the right side

	[scconfig]
		-Fix: librnd_ver.o depends on installed librnd config.h so it gets recompiled on librnd version change
		-Fix: implicit declaration of librnd ver req min
		-Fix: remove #warning, it's not portable

	[tests]
		-Fix: conftest implicit declarations made OSX fail to compile
		-Fix: conf test: list overwrite sets the higher prio on the subtree that's actually used for the overwrite
		-Update: drc_query fullpoly test for more detailed cleared-out-of-existence message
		-Add: OSX library path workaround: be able to inject SHELL in Makefiles and use pcb-rnd.wrap in shell scripts (when wrapper is available)

pcb-rnd 3.0.3 (r36039)
~~~~~~~~~~~~~~~~~~~~~~
	[act_draw]
		-Fix: typo in PolyBool help/syntax text (wrong action name)

	[build]
		-Add: check for librnd version, require 3.1.0
		-Add: config.h has a #define for libxml2 presence so that plugins with partial libxml2 dependency can enable/disable parts of their code
		-Add: when libxml2 not found, mention that amf model loading is also disabled

	[core]
		-Fix: don't attempt to xor-draw hole of a padstack if the prototype is missing
		-Fix: do not attempt to draw slot if proto is NULL
		-Fix: don't call extobj float pre if there's no valid object
		-Fix: plug_io warns for underspecified format only if the format yields multiple yields of _different_ loader functions
		-Fix: undo bug: when rotating a padstack off-center so that the padstack's coords also change (move), undo did not move it back, only rotated it back
		-Fix: buffer: make sure to not load config when importing a board into paste buffer
		-Fix: buffer: when loading a board into buffer, skip side effects such as design dir setting and routing style updates
		-Fix: text rotatation: wrong clamp on negative rotation angles resulted in inverted angle
		-Fix: buffer rotation: set bottom side text rotation to negative angle so it rotates the same way as top side text
		-Fix: change default rendering order so that paste is cut through not only by mech (slots) but holes too
		-Fix: remember when picking up buffer from the bottom side and when converted to subc, put subc-aux on the bottom side too
		-Fix: convert-to-subc: subc aux layer creation: broken x/y vectors on the bottom side
		-Fix: convert-to-subc: when converting a subc on the bottom side and have to create refdes text, place that on bottom side as well as that's the primary side for this subc
		-Fix: unbind board.c events on exit
		-Fix: wrong uninit sequence caused inf loop on exit
		-Fix: lock-floaters and only-floaters are exclusive settings; the menu shall use the display() action instead of the more generic conf() action so that the xor logic is executed
		-Fix: library sorting: keep configured order of roots to reflect search order in the library window
		-Fix: subc preview draw: reset info to all 0 because there may be fields with side effects in pstk draw that we don't explicitly set
		-Fix: do not crash on failed pstk conversion (freeing shapes from uninitialized memory)
		-Split: subc preview draw: padstack draw code into a separate function as it will need to be called multiple times for various layers
		-Add: subc preview draw: render only visible layers
		-Add: subc preview draw: draw mask & paste of padstacks when visible
		-Add: subc preview draw: pass on host layers for coloring padstack to match user preference (current board)
		-Add: subc preview draw: draw on-padstack objects too on top mask and top paste
		-Add: footprint lib code: make it possible to remember format for footprint entries so loading from the lib doesn't need to try different formats again if they were tested during mapping already
		-Add: check for librnd minimum version runtime - just in case the executable was compiled with a different version than installed runtime
		-Add: include librnd full version string in program ID (CLI: --version; GUI: about box)
		-Add: if gtk2 HID is not available, also try gtk4 HID as fallback

	[diag]
		-Del: conf diagnostic actions - they got moved to librnd 3.1.0

	[dialogs]
		-Fix: 'save as' initial format guess hides the guess failure message initially (format is surely known) with both the old and the new fsd
		-Fix: create doc layer groups on top, bottom and global for the library window footprint preview to serve as a fallback for any courtyard, keepoiut or custom layer (in modern footprints)
		-Fix: scroll the tree table widget, not parent box; it's possible from librnd 3.1.0 and fixes scoll-with-arrow-key
		-Add: library dialog: subc preview layer visibility control checkboxes so that unwanted layers can be hidden from the preview
		-Add: library dialog: get default preview checkbox settings from config
		-Add: library preview: copy layer colors from the current board
		-Add: preferences: modular tab system; moved generic tabs from pcb-rnd to librnd

	[doc]
		-Update: bridges and format list: eagle xml .lbr load
		-Update: datasheet for altium boards and protel 98/99 boards, export_stl's amf
		-Update: action reference: moved some action between plugins
		-Add: tutorials link in the "menu" with cuvoodoo's 'getting started' video is the main tutorial now

		-Fix: subc rotation is negative on the bottom side
		-Add: abstraction layer for different formats; be able to load multiple model formats, independently of export format
		-Add: support for the amf format (model load and export)
		-Add: vertex hash for amf and later projector
		-Add: model load fallback mechanism: try model format matching the output format first then fall back to other model formats
		-Add: output-only format: projector(1)

	[export_xy]
		-Fix: pick up bottom-pnp-origin (without suffix)
		-Cleanup: get rid of xray_theta (always 0)
		-Add: support for optional xy::rotate and xy::translate attributes
		-Add: --vendor argument so multiple rotate and translate can be used
		-Add: xy::translate needs to be rotated around the pcb-rnd origin of the subc because the p&p machine will rotate around the translated point while pcb-rnd rotates around the pcb-rnd origin
		-Add: generalize board level pnp-origin function so it will be reusable for multiple origins
		-Add: new substs: side-x, side-y, side-padcx, side-padcy that use the bottom-pnp-origin(-*) for reference
		-Add: %side-rot% and %side-negrot% substs
		-Add: %side-negrot180% subst
		-Add: %subc.side-rot180% subst that reproduces original gEDA/pcb behavior

	[find.c]
		-Fix: bloated poly vs. poly jump got "too accurate": a thermal doesn't really overlap with the object so it didn't find connection; cheat with a few nanometers of extra bloat
		-Fix: poly-poly bloated intersect: don't attempt to use negaive thickness in intersect tester line
		-Fix: bloat override on "line vs. polygon" check so that the bloat adjustment used to overcome numeric precision problems can be applied
		-Fix: use minimum line thickness 4 nanometer instead of 2 for line-to-poly to avoid self intersecting lines
		-Fix: padstack zero-thickness line edge should be taken as 4 nanometer so the line intersection test is actually done
		-Cleanup: const correctness on find context and missing cast to any-obj
		-Add: TODO on making bloated poly-poly test cheaper

	[footprint]
		-Add: stl models for 1206 and SOT23

	[fp_fs]
		-Add: remember format for footprints bundling in multi-footprint file libs

	[io_altium]
		-Fix: handle all types without aborting on bool conversion (broken user input shouldn't abort)
		-Change: plgin enabled by default, now that we depend on librnd 3.1.0

	[io_bxl]
		-Fix: don't run an extra round of parsing on error

	[io_dsn]
		-Fix: wrong return value for boolean func is_protected()
		-Fix: loading a board: this format doesn't have a design conf tree in the file, still some config nodes are loaded from other fields; make sure plug_io won't reset the subtree
		-Fix: read all rules, not only the first one from structure/rule
		-Fix: when loading a board, make sure subcircuits have the sub-aux objets so that subc orientation and side are correct
		-Fix: activate bottom side mirror fix in the placement lib so that bottom side rotation+mirror is done right
		-Fix: for proper bottom side rotation we need the rotate_first placement strategy, not the mirror_first
		-Fix: enable the "space omitted before opening brace" fix for reading eagle produced dsns now that librnd 3.1.0 has the required API
		-Cleanup: function with no return value should be void

	[io_eagle]
		-Fix: wire layer allocation fail should print the actual layer number not a random number
		-Split: function that reads a single package from library read code so it can be reused for loading a single footprint for a lbr file
		-Add: set default units to mm for footprint/lib files
		-Add: footprint map implementation (somewhat slow as it requires xml parsing)
		-Add: layers subtree parse: create bound layers when data is not NULL (for footprint file parsing)
		-Add: get_layer() handles footprint context if pcb is not available (when we are reading a footprint file)
		-Add: parse the package subtree when laoding a footprint file
		-Add: tolerate missing pcb on package parsing for layers and extents (for loading footprints)
		-Add: support for loading binary libs
		-Add: create layers on get_layer even if they were not in the layer subtree (some binary libs do not have a layer subtree)

	[io_kicad]
		-Fix: do not attempt to create empty text objects while loading a board or footprint

	[io_lihata]
		-Fix: do not load layer attributes when loading a board into buffer (it's a side effect that would affect menus)
		-Fix: loading a pre-v5 board won't have a design conf tree in the file, still some config nodes are loaded from other fields; make sure plug_io won't reset the subtree
		-Fix: pre-v7 did not have pixmap support, do no write the pixmap subtree
		-Cleanup: use rnd_trace for persistence format preservation debug
		-Add: persistent write: preserve numeric format of arc angles (as double)

	[io_pcb]
		-Fix: print an error and skip empty text objects while loading (would result in an object that's extremely hard to handle on the GUI)

	[lib_netmap]
		-Add: option for alternate y mirroring on bottom side footprints (for io_dsn fix)

	[libcdtr]
		-Fix: debug draw should use coords and not rely on int
		-Fix: don't hardwire point violation circle radius in debug draw, calculate it from drawing size
		-Add: tester command for polygon triangulation
		-Add: tester command to draw violations in animator
		-Add: Wojciech's fix for floating point precision caused inifinite looping on poly triangulation
		-Add: regression tests for the lib compiled with doubles

	[librnd]
		-Cleanup: use rnd_hid_fileselect() instead of direct call to hid->fileselect for easier forward porting at version bmp librnd 4.0.0

	[plugins]
		-Update: change plugin state from "WIP" to "works" on plugins that got enough mileage of testing: export_openscad, export_stl, import_sch2, import_ttf, io_bxl, io_pads

	[propedit]
		-Fix: recurse to editable subcircuit objects on the first level of subcircuits (floaters, padstacks) when dealing with selection
		-Cleanup: reduce code duplication in executing set/del/map on selected objects, so that there is only one TODO#28 to make sure it's always handled the same

	[query]
		-Cleanup: remove local_str in favor of const string return from thermal API

	[renumber]
		-Fix: do not ask for overwrite permission twice
		-Fix: pass on subc to change name on as ptr2 as callee expects that (fixes a crash)

	[shape]
		-Fix: make "last point" coords persistent while drawing a rounded rect so in "Majenko's round corner case" when two rounding arcs meets exactly there won't be coord duplication making the resulting poly invalid

	[tests]
		-Fix: don't try to directly compile the diag plugin code into the tester but depend on librnd
		-Fix: ignore empty lines printed as part of error messages for the menu test
		-Fix: fitler out pup loading error messages from the output in tests doing output comparison: some unrelated plugins may be broken
		-Update: bottom side subc rotation error in xy due to loading from pcb format was broken


pcb-rnd 3.0.2
~~~~~~~~~~~~~

Out-of-order bugfix release: 3.0.1 + a single bugfix

pcb-rnd 3.0.1 (r35718)
~~~~~~~~~~~~~~~~~~~~~~
	[ar_extern]
		-Add: run freerouting.cli and freerouting.net
		-Add: provide 3 progress bars for more detailed progress report

	[core]
		-Fix: padstack preview draw should draw slot shapes when hole drawing is enabled so slots are not invisible
		-Fix: footprint mass-import (ElementList()), frame placer: line up new subcircuits close to the frame even if the subcircuit origin is far off from 0
		-Fix: footprint mass-import (ElementList()), frame placer: space subcircuits at a fixed distance, accurately along the frame
		-Fix: menu actions: when switching drawing mode conf, also force a redraw to make sure the new settings take effect on screen (fixes lesstif no refresh bug)
		-Fix: find.c: poly padstack shape vs. polygon intersection check does not ignore bloat anymore (fixes: poly padstack vs. poly clearance vilation missed in drc checks)
		-Fix: find.c: poly-poly bloated isc failed to find some matches because of search box was not bloated up (affected axis aligned rectangles mostly)
		-Fix: find.c: don't run the padstack thermal optimization if bloat is non-zero - bloat may be a game changer in whether the padstack touches the sorrunding poly
		-Add: when xor-drawing padstacks, draw hole or slot; this helps positioning vias but also acts as the only indication for a copperless mounting hole
		-Add: utility function to check if a text object has invalid chars in a font
		-Add: pcb_thermal_chars2bits() that can convert the 2 byte text representation of per layer thermals back from text to bin (used in query and later in propedit)
		-Add: a variant of the therm bits to chars conv function that returns const char * to simplify memory management in query

	[dialogs]
		-Fix: fontsel: missing else made per object fontsel unavailable

	[doc]
		-Del: web client from the bridges drawing - won't be finished any time soon
		-Add: document the new query function for invalid characters in text
		-Add: BXL in bridges
		-Add: bridges: separate group for external autorouters

	[drc_query]
		-Add: DRC rule for finding text with invalid chars

	[export_stl]
		-Fix: coord range to let the GUI enable user to set anything positive for min hole and slot size
		-Fix: coord range for override-thickness so the gui lets the user set anything positive

	[import_pxm_gd]
		-Fix: used the wrong feature macros for deciding if formats are available (librnd separation related bug)

	[io_dsn]
		-Fix: implicit declaration on rnd_strcasecmp()

	[io_tedax]
		-Fix: autorouter config import: use the right fields for default value and max value
		-Fix: autorouter config import: convert coord values from mm to internal
		-Add: implement loading arcs from route result

	[propedit]
		-Add: padstack/thermal/lid/ subtree

	[query]
		-Add: glue function for counting invalid characters in a text

	[autoroute]
		-Fix: do not generate invalid bounding box for terminals with certain copper/clearance ratio
		-Fix: do not ruin the head of the netlist with NULL while trying to remember the last valid net

	[conf]
		-Change: rename pcb-conf.lht to conf_core.lht for clarity

	[core]
		-Fix: Display(RealignGrid): do not force a new click; when invoked by hotkey or action, just use the current position of the crosshair; this allows the user to take advantage of a coarse grid and object snap
		-Fix: remove obsolete checks and restrictions on last copper layer(group) removal
		-Fix: don't let the One Subcircuit removed by the operation code in footprint edit mode
		-Fix: obj hashing: coord neq comparison should apply the same 4 nanometer tolerance as hash calculation to overcome rounding problems in rotation/mirroring
		-Fix: enfroce clearance: enable find-through-rats so disjunct same-net objects can be connected
		-Fix: pstk rendering: always set cap style for the unplated sign else the GUI will assert when the drawing contains only unplated holes (e.g. all other layers are turned off)
		-Fix: pstk: get clearance at layer: do not crash if the padstack does not have a global clearance and there's no shape on the given layer
		-Fix: find.c: corner case on any-layer pstk line shape ISC check on mech (hole/slot) - the layer of the line shape is not known, query mech shape on any layer
		-Fix: extobj: do not let extobj floaters be moved to another layer (would break edit objects being edit objects in most extobj implementation) - rather ask the user to change layer bindings instead
		-Fix: pcb_subc_alloc_layer_like() should do the layer binding properly when source layer is not a subc (bound) layer but a real board layer
		-Fix: polygon clipping: when an object can not be cleared from a polygon, don't abort the whole clearing process, only abort clearing that specific object (fixes a bug with one non-clearing line blocking other objects to clear)
		-Fix: 'move selected to current layer': do not stop after the first object moved
		-Fix: draw: local default xform uninitialized memory when input xform is NULL
		-Fix: hshadow of a padstack is always connected to the plated hole of the padstack (shape can not be off-center)
		-Fix: poly validity check low level: check outer countour then holes separately, then check each hole against other holes and the outer contour for intersection
		-Fix: adding a hole in a polygon shouldn't remove polygon attributes
		-Optimize: find: intersection between pstk and poly: skip expensive polygon calculation if there's a clearance (and no thermal)
		-Import: is-angle-in-arc function from libgrbs
		-Add: alternative (main) name for Display(ToggleGrid): Display(RealignGrid) for clarity
		-Add: pcb_arc_get_angle() that calculates the angle for an x;y - it's more than just an atan2() because of the broken coordinate system we use
		-Add: ExecActionFile() alias for ExecuteFile() - this one should be the same in all Ringdove apps
		-Add: generic point-on-object utility function
		-Add: pcb_arc_get_xy() because of the strange coordinate system we use
		-Add: view: remember netnames when the view is about a net
		-Add: pcb_poly_to_polygons_on_layer() should return the newly created polygon, the hole-destroys-attribute bugfix will depend on it

	[data]
		-Cleanup: remove /data; move the stock desktop file and file(1) magic to doc/resources/

	[dialogs]
		-Del: manage plugins dialog: moved to librnd
		-Fix: typo in DrcDialog() syntax text
		-Fix: close file after writing padstack
		-Fix: padstack proto lib dialog action: no-argument call should default to the new 'auto' mode, which selects either the board (in board edit mode) or the first subc (in footprint edit mode) as target; fixes the bug thta in fp edit mode it popped up an irrelevant context
		-Fix: layer binding dialog crash on empty name
		-Fix: layer binding: when figuring intern copper layer offset for the dialog box, set it from top or bottom, never from global
		-Fix: layer binding: react on changing layer offset (it is a spin widget, compound, so the original test falesly thought it was already handled)

	[doc]
		-Fix: packager's auto gen script: if the checkout is not configured, try /usr or /usr/local
		-Fix: pcb-rnd.1: the full name of the hid is gtk2_gdk
		-Fix: packager's doc generator: $C hint is /etc/pcb-rnd as the default has changed
		-Fix: packager's doc: HID plugins are prefixed with librnd3-, not pcb-rnd-
		-Fix: packager's doc: meta pkg needs to depend on the gui lib so the default install works with gui

		-Fix: broken link: we don't really have a prop list in query yet
		-Fix: query: mklist() explanation (copy&paste error)
		-Fix: query lang has no native comment, only the file format that contains the script may have comments

		-Update: ircnet is no longer available for support
		-Update: INSTALL for the separate librnd dependency
		-Update: bridges: dsn board and pads ascii board are both bidirectional

		-Add: dialog: DrcQueryRuleMod(remove) to remove rules
		-Add: dialog: remove button for rules in the rule list dialog

	[export_dsn]
		-Del: reimplemented in io_dsn

	[export_gerber]
		-Fix: don't hardwire lib_hid_common dependency by C call (on xpm name resolution), rather use an action - GUI is not mandatory for gerber exporting

	[export_lpr]
		-Fix: dynamic allocate values[] on start, querying export_ps option list len (fixes a buffer overrun)

	[export_svg]
		-Fix: photo mode: did not work due to a fix went wrong years ago on compositing layers
		-Fix: photo mode: missing holes
		-Fix: photo mode: flipped export: move bottom copper layers on top of the visibility stack for proper coloring
		-Fix: offseted polygon vertex coordinate transformation applied y-flip before the offseting which catapulted polygons out of their intended location in flip-mode renders
		-Add: photo mode: blend noise on top to make the result look less artificial (optional)

	[footprint]
		-Fix: tru-hole -> thru-hole rename in make install

	[import_dsn]
		-Del: session import (moved to io_dsn)

	[import_gnetlist]

		-Cleanup: remove unused RND_DAD_CFG_NOLABEL
		-Cleanup: remove HL_* from the build - these were relevant to librnd
		-Cleanup: remove $LC and $LP from packager's doc - we are not installing anything librnd anymore
		-Cleanup: doc: replace developer doc that got moved to librnd with placeholders with links to the new place
		-Change: switch over central build and scconfig detections to exclusively use installed librnd instead of depending on a local svn extern
		-Update: util makefiles for separate librnd install (affects gsch2pcb-rnd and bxl2txt)
		-Update: follow librnd API changes for 3.0.0 
		-Update: make local tests compile and run with librnd3
		-Update: packaging doc: deps for the external librnd3 package names
		-Add: temporary glue code in gsch2pcb-rnd for -l linking of librnd-hid
		-Add: specify host app revision
		-Add: set LIBRND_PREFIX in Makefile.conf (for tests)
		-Add: Makefile.conf delivers the full path to librnd.mak to simplify test Makefiles
		-Add: gsch2pcb-rnd sets rnd_app package, version and revision
		-Add: import librnd's plugin state list before calculating plugin deps
		-Add: document using non-standard prefix librnd installation
		-Add: scconfig hooks.c should create a dedicated variable with the full path to librnd scconfig templates, and that shouldn't hardwire /lib but should use arch specific libdir (e.g. lib64 if the user specified that)
		-Add: document --libarchdir match requirement
		-Add: static link librnd option: also use librnd.mak for the -L's and -l's
		-Add: doc: do an svn checkout from librnd action doc and include librnd actions in the action reference (in a separate details section; marked as RND on the list)


	[menu]
		-Add: dedicated text/terminal ID edit submenu for {e t} in the edit menu

	[pcblib]
		-Rename: pcblib to footprint; by the default config footprints are loaded from: footprint/ from the board file's directory (for existing board files); user dir ~/.pcb-rnd/footprint (and ~/pcblib for compatibility); ../footprint (for running from source); $SHARE/pcb-rnd/footprint (system installed)

	[plugins]
		-Cleanup: rename ultimate fallback export basename from pcb-out to pcb-rnd-out in all export plugins

	[puller]
		-Cleanup: remove glib's hash table, use genht's htpp
		-Cleanup: remove glib dependency from compilation

	[query]
		-Fix: advanced search fialog: do not crash on converting invalid query expression back to gui
		-Fix: advanced search dialog: don't ruin user's expression on compilation error
		-Fix: net_len: net seg len API needs to get query context else it can not return the segment struct, which depends on the context
		-Fix: net_len: properly mark HUB segments and remember at least two connected objects
		-Fix: net_len: disable one of the hub removal heuristics because it never removed the hub but the next object
		-Fix: net_len: special casing padstack <-> traceobject connection: it is common that trace object only slightly overlaps with the padstack (e.g. via) because of a (now ignored) dog leg connection
		-Add: net_len: public API call for accessing low level net segment mapper
		-Add: net_len: remember junction hubs and set junction glue fields
		-Add: net_len: optional rat inclusion (useful for net mappers)
		-Add: net_len: decide and return which of the two objects is a hub object in a T junction
		-Add: net_len: detect invalid junction (X-junction, e.g. when two lines intersect in the middle)
		-Add: net_len: helper function to decide if an object pair is a padstack and a trace object fully overlapping with the padstack
		-Add: net_len: pre-map trace objects fully overlapping with padstacks so they can be ignored later
		-Add: net_len: internal API config option for 'stop at terminal' preference
		-Add: expose val_free_fields for callers handling query results
		-Add: expose low level iterator reset and upgrade it to work with persistent iterators as well
		-Add: expose a low level free() for iterator fields

	[route_style]
		-Fix: use the new 'last route style selected' cache to get the right style selected when when multiple route styles match
		-Fix: non-strict route style match: if a route style doesn't have via proto set, it matches any pen via proto
		-Fix: do a route style update after creating a new style to make sure the GUI shows the right style
		-Fix: when editing a route style using the dialog box, never jump target to a different style only because of matching fields

	[scconfig]
		-Fix: never use -ansi in the c99 compilation: recent gcc generates an error on the ((unused)) attribute for that
		-Fix: do not crash when value is missing for --key=value custom args
		-Fix: don't run configure program if it failed to compile
		-Add: ./configure needs to figure LIBRND_PREFIX before compiling scconfig as parts of the final ./configure binary is coming from librnd
		-Add: be able to compile local scconfig with librnd installed to non-standard prefix
		-Add: print --prefix and --confdir in configuration summary
		-Del: local computation of the final conf dir: librnd3 does that in an unified way and /local/confdir has the final value

	[svg]
		-Fix: photo mode export in flip mode: invert photo offset Y on polygons so that the shadow is on the right corner

	[tests]
		-Fix: uniq_name doesn't depend on system installed genht
		-Optimize: speed up pcbflags test by removing library search and default font using command line config

	[tool_std]
		-Fix: some old scripts depend on action Mode(PasteBuffer) while our tool is called "buffer" only; add an invisible alternative tool called PasteBuffer so old scripts work

	[util]
		-Fix: typo (excess $ROOT for librnd paths) in Makefile template
