Duncan Wood / UniGraphic

Basically i glued Peter Drescher and Simon Ford libs in a GraphicsDisplay class, then derived TFT or LCD class (which inherits Protocols class), then the most derived ones (Inits), which are per-display and are the only part needed to be adapted to diff hw.

Revision:
34:67b3634507da
Parent:
27:acb2594b8aa4 
The libraries used would not output %.  I tried escaping it but nothing worked. So I changed the & in the font and used that.  Not cleaver I know.  I don't recommend this to anyone.

Who changed what in which revision?
