Revision: 1.304
Committed: Wed Sep 12 19:51:41 2007 UTC (16 years, 9 months ago) by sasha
Content type: text/plain
Branch: MAIN
Changes since 1.303: +12 -4 lines
Log Message:
Got rid of want_full_refresh - no longer needed; removed setting want_refresh in bgPixmap.apply() - is done in Expose event handler instead; Fixed clearing background to clear vt as well; added check for pixmap origin in font_xft::draw(); added window_position_sensitive() to bgPixmap for consistency
