esp. wrt. 10 bpc framebuffers, identity lut's, pixel passthrough etc.

-> 64-Bit kernel driver for OSX 10.8+ rebuilt.

(cherry picked from commit 6732afbf7b0b6b9245bf8e8a1d6dd0a0f5e4f1ec)

-> Incorporates all the AMD DCE-4+ display engine handling fixes.
-> Incorporates kPsychGUIWindow fix for Linux.
