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.
Fix compile error with wrongly named include file
Revert lld_gdisp naming convention to gdisp_lld to fix problem and be
consitant with all other low level drivers.
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.
