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.
