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.
