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.
New low level driver interface: Only Win32 ported currently
Significant reduction in GDISP stack usage
Improved performance particularly for native streaming drivers
New circle, ellipse, arc routines (draw and fill) that are significantly more efficient and don't overdraw
New arc draw algorithm that measures angles correctly.
New arc fill algorithm for that actually works without overdrawing or gaps.
Much more to come...
