Andreas Kling 6a5d92f0ad WindowServer+LibGUI: Allow changing whether windows have alpha channels.
Use this in Terminal to tell the window server to not bother with the alpha
channel in the backing store if we're running without transparency.
Semi-transparent terminals look neat but they slow everything down, so this
keeps things fast while making it easy to switch to the flashy mode. :^)
