 - Increased the frame buffer size to 192KB.
 - Removed a superfluous VIDEO_FREEZE call in the replay buffer.
 - Added French language texts (thanks to Jean-Claude Repetto).
+- Modified OSD to use 2bpp windows (4 colors) in order to work with less
+  memory, allow a larger OSD window and be faster. The group separators in the
+  "Channels" menu had to be given a different color.
+- Moved the channel display to the bottom of the screen.
