various improvements:

Browse source 
- speedup in slide mode: don't paint desktops which are not visible
- key events are not dropped during start phase
- parts of windows from different desktops are faded in/out during start/stop animation
- manual (mouse) rotation is reverted in stop animation
- Cube Cap Texture is positioned oriented towards desktop 1
- fix artifacts from different desktops after stop animation
