- changed pad classification in instances from bare/other to copper/special - moved LAYER_* definitions from layer.h to layer.c - after instantiation, we perform sanity checks on pads and remove layers from coppery pads that are handled by a special layer - fped.y: the line number in objects was never set - overlap.c: fixed overlap calculations - gui_tool.c: end_new_pad didn't initialize the pad type git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5635 99fdad57-331a-0410-800a-d7fa5415bdb3
