Commit:	6db067a90fd85c72e6b2d9d6337ea49a76e8783c
Message:	More work on holes: added documentation and Postscript output. - overlap.c (inside, test_overlap): check for instance type - overlap.c (inside, test_overlap): support hole instances - README: put a pointer to the GUI description at the beginning - README, gui.html: documented role and creation of holes - inst.h: holes can now link to pads and vice versa - hole.c, obj.c (instantiate): connect holes with pads and apply consistency checks - postscript.c: added output for holes - icons/hole.fig: make hatched surroundings of hole look more round git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5940 99fdad57-331a-0410-800a-d7fa5415bdb3

	261
	262	Holes can be used for through-hole pins or for mechanical support.
	263	In the former case, the hole must be placed inside a pad. Only one
	264	hole per pad is allowed. Mechanical holes must be outside any pads.
	265
	266	Through-hole pads are always present on both sides of the board, i.e.,
	267	when fped generates a KiCad module, the surface layers of a pad
	268	containing a hole are propagated to the opposite side of the board.
	269
	270	Holes have the same shape as a rounded pad and their geometry is
	271	defined in the same way:
