Add polygon drawing
Add convex polygon filling
Start support for a monochrome display
Move gdisp doxygen to header file
Restructure the balance between gdisp.h and gdisp_lld.h
Remove old extern font definitions (now always use gdispOpenFont)
Make public the GDISP structure and change macros to suit (faster for
the application).
gdispQuery is now optional.
Add option GWIN_BUTTON_LAZY_RELEASE. When set to true in gfxconf.h it
changes gwin button behaviour to not require the mouse/touch be over the
button when it is released.
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.
GINPUT when being exclusively polled by the application, did not allow
pre-emption of the main thread and therefore some platforms (Win32) the
mouse/toggle stopped working.
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.
