gEDA-user: pcb-20070208 snapshot

[Dan McMahill <dan@xxxxxxxxxxxx>]

Hello,

I have uploaded a new pcb snapshot to sourceforge.

The release notes below don't really do justice to the huge amount of 
work that harry and DJ both put in between the last snapshot and now. 
harry implemented polygon clipping which has greatly improved how PCB 
deals with polygons.  Among other things issues with some board houses 
not fully supporting RS-274-X should not be a problem now.  Also islands 
in polygons created by cutting the polygon with traces are removed and 
the connectivity checker correctly deals with this case.

Just in time for this weekends code sprint!

Have fun

-Dan

Release Notes for PCB snapshot 20070208
========================================================================
- Add polygon clipping code.  This is a big change to how polygons are 
handled.
  The new code now removes islands and correctly identifies open 
circuits caused
  by a trace fully cutting through a polygon.  In addition, the 
RS-274-X output
  is now simpler and works with some board houses that use older 
non-conforming
  sofware.  Different styles for thermal reliefs are also now supported 
as part
  of the polygon clipper code.
- Add support for plugins
- Many improvements to the autorouter.
- Various improvements to the trace optimizer.
- Add a fontmode for editing pcb fonts
- Add progress() hook to HID structure
- Fix a bug with non-functional windows on some window managers commonly
  found on OS-X
- Add support for controlling pcb via dbus
- Fix various bugs which would cause a crash
- Add --scale for postscript scaling
- Intercept window manager delete events with the GTK gui
- Scan the .pcb file for a FileVersion value.  This is not written out yet
  but will be in future versions.
- Warn if non-manhattan lines are trying to become pads.
- Allow no-solder paste pads to support fiducials
- Report in mm or mils as selected by user
- Allow reordering of layers
- add some more QFN packages
- fix building with sun studio c compiler
- Made a pcb installation be relocatable.
- Convert the m4 libraries to newlib libraries as part of building a 
distfile.
  The m4 libraries are still considered the sources and as such are still
  distributed but this eliminates the need for m4 at runtime for 
footprints.
- Got rid of the pcb wrapper script around pcb-bin.
- Remove some old footprints of questionable naming, accuracy, or 
usefulness.
- Get the autosave/backup code working on all GUI's
- Fix some drill size rounding in the reports
- Changed the backup file name to be derived from the .pcb file name
- Added a command line option for DrawGrid
- Fix logic for adding new ratlines
- Fix gtk grid when board is flipped
- Add "find" and "rip-up" buttons to the netlist window
- Draw plated holes when exporting
- Fix some bugs when converting selection to element
- Fix build on cygwin
- Enhance the win32/build_pcb script used to generate a non-cygwin windows
  installer.
- Make pcb work under non-cygwin windows
