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.
Add GDISP font routines to Open and Close a font by name.
Allows wildcard searching for fonts.
Old global font variables are now only optionally included (soon to be
deprecated).
More demo fixing
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.
Emulates 4 toggle switches and 4 momentary action buttons in the Win32
driver.
These are represented as a row of buttons under the GDISP display
window.
These are implemented as GINPUT Toggle driver (not as GPIO pins).
