- make_var now sets up all back pointers, so we don't crash when deselecting a variable (this bug was uncovered by cleanup in the previous commit) - report_parse_error didn't print a newline at the end of the message - introduced frame reference selection and the data structures needed for it - bounding box calculation of arcs used x for y - added frame reference selection example quad.fpd git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5377 99fdad57-331a-0410-800a-d7fa5415bdb3
