Commit Message

Handle ARGB desktop windows correctly.

core: compiz::private_screen::DesktopWindowCount - provide methods to
increment or decrement desktop windows based on their visual type.

desktopWindowCount () now returns the number of RGB and ARGB desktop windows,
argbDesktopWindowCount () just returns the number of ARGB desktop windows.

If they are equal, the only desktop window is ARGB.

opengl: Draw the root window background if the desktop window is ARGB.
wallpaper: Lie to core and say that our fake desktop window is RGB so that
core does not draw the root window background. Paint the desktop wallpaper
beneath the desktop window so that the ARGB desktop window is visible on
top of it.

Tests added for the increment/decrement logic in DesktopWindowCount.
