- README: described use of semicolons
- README: added that loops can also execute zero times - accept labels only at the beginning of a line - rectangles and lines no longer use the bounding box for drawing (caused offset problems since we now correct for the line width) - dist_rect and inside_rect no longer require their input pre-sorted - pad instances now have their own structure and no longer abuse the bounding box to know the pad coordinates - Makefile: use $(GEN) for fig2dev, to reduce chattiness - when dragging a point, the symbol is now adjusted accordingly - added moving of rects, pads, circles, and arcs - added creation of pads - moved rotate_r from gui_inst.c to coord.c - new function "theta" that combines most of the angle calculations - save_pix_buf: y < 0 clipping changed width, not height git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5386 99fdad57-331a-0410-800a-d7fa5415bdb3
