You can now have a main color display and a secondary monochrome display.
You can now optionally set GDISP_PIXELFORMAT to any color or grayscale format for your application and the driver will internally convert to the display hardware format.
Prepare for (but not yet complete) supporting a different high level GDISP pixel format to the low level driver format.
This will be useful in multiple display scenario's where displays have different pixel formats.
