- postscript.c: added some code for frame display, but I'm not happy with it
- postscript.c: moved tedious "... maxfont maxfont ..." into new function "boxfont" - postscript.c: "hcenter" was way off for diagonal text - postscript.c: "realsize" didn't take into account the effect of rotation and returned only the x component in the original coordinate system - fped.c: feed a dummy argv to gui_init, so that we can parse the arguments before deciding whether to bring up the GUI - fped.c: don't bring up Gtk+ if we're not going to use it git-svn-id: http://svn.openmoko.org/trunk/eda/fped@5578 99fdad57-331a-0410-800a-d7fa5415bdb3

@ -36,8 +36,6 @@ Bugs:
|
||||
- whenever we call parse_* for input parsing, we may leak lots of expressions
|
||||
- can't edit measurement labels through the GUI
|
||||
- unbalanced parentheses in text throw off Postscript syntax
|
||||
- when starting, Gtk+ may issue many "extension [...] missing" warnings, which
|
||||
can (and did) hide warnings about real problems
|
||||
|
||||
Code cleanup:
|
||||
- merge edit_unique with edit_name
