Create global include file called gfx.h which knows about sub-system dependancies. Deprecate Touchscreen (GINPUT touch is now working properly) Merge Graph into GWIN Change directory structure to reflect sub-system structure Many small bugs fixed Split Nokia6610 gdisp driver into GE8 and GE12 controller versions Fixed broken demos. GFX sub-systems are now clearly defined and new ones should be much easier to add.
