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.
GDISP:
Fix gdisp???Arc to use (possibly) hardware accelerated routines.
Fix Arc orientation so 0 degrees is on x axis and 90 degrees points to
the top of screen (instead of the bottom).
Add rounded box routines (if ARC support is turned on).
Add a gdispDrawStringBox to match the gdispFillStringBox routine.
Repair prototypes in wrong place in gdisp.h
GWIN:
Extract the concept of a Window Handle to allow many new features.
Allow dynamic creation of window objects as well as static
initialisation.
Seperate the console code into a console specific window type.
Add buttons as a specific window type. The drawing code is complete, the
input (touch or mouse) is still to be implemented.
Implement gdispFillArc in gdisp.
Added gwin (GFX_USE_GWIN) - adds a window based drawing layer to GDISP.
GWIN also support chprintf text drawing like console.
