----- Killed UI frontbuffer draw
The interface toolkit was drawing all live updates (while using menus/buttons)
in the frontbuffer. This isn't well supported cross-platform, so time to be
killed once. Now it uses *only* glReadPixels and glCopyPixels for frontbuffer
access.
Live updates or menus now are drawn in backbuffer always, and copied to
front when needed.
NOTE: it was tested, but needs thorough review! On PC systems I suspects
backbuffer selection to screw up (check!). On SGI/SUN workstations it
should work smooth; but I need evidence
----- Smaller fixes;
- AA fonts were garbled on ATI systems. Now the AA fonts are drawn exact
on pixel positions. Needs the new FTGL libb too, patch is on maillist
- Rounded theme uses antialiased outlines
- Pulldown and popup menus have nice softshadow now
- New button type 'PULLDOWN', thats the one that callsup a pulldown menu.
Should be added to themes, as is the full menu/pulldown drawing
- Screendump for 1 window does the full window now, including header
- Empty pulldowns (for example running blender without scripts) give no
drawing error anymore
For review & fun;
- added curved lines as connectors, for Oops window
