Bug#622575: Rotating display should automatically switch to appropriate vrgb subpixel antialiasing

[Josh Triplett]

Package: gnome-settings-daemon
Version: 2.30.2-3
Severity: wishlist

Currently, after rotating the display with "xrandr -o left" or "xrandr
-o right", gnome-settings-daemon continues using the same subpixel
antialiasing mode.  By definition, if the subpixel mode worked before
rotation, it won't work after rotation.  Thus, I propose that
gnome-settings-daemon should automatically switch to the appropriate
subpixel antialiasing mode when the screen rotates.

Similarly, gnome-settings-daemon should switch from rgb to bgr
antialiasing when inverting the screen.
