- README, fpd.l, fpd.y: added directives "allow touch" and "allow overlap" to make overlap checking more permissive - dump.c (dump_allow, dump): generate "allow" directive - obj.h, obj.c (allow_overlap): added global variable for strictness of overlap checking - overlap.h, overlap.c (overlap, ...), layer.h, layer.c (refine_layers): strictness of overlap checking is passed as an argument - hole.c (check_through_hole), layer.h, layer.c (refine_copper), obj.c (instantiate): updated callers of "overlap" to provide "allow" argument git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5974 99fdad57-331a-0410-800a-d7fa5415bdb3
