annotate src/vdb-win32.c @ 5044:e84a30b0e4a2
remove duplicative code in change_frame_size()
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-15 Ben Wing <ben@xemacs.org>
* frame.c (change_frame_size_1):
Simplify the logic in this function.
(1) Don't allow 0 as the value of height or width. The old code
that tried to allow this was totally broken, anyway, so obviously
this never happens any more.
(2) Don't duplicate the code in frame_conversion_internal() that
converts displayable pixel size to total pixel size -- just call
that function.
