'' '' Points, lines, arcs, sprites, text, and polygons are rasterized into '' a specified stretch of memory which serves as a generic bitmap buffer. '' '' The bitmap can be displayed by the TV or VGA driver. '' To date, the C library version has been tested on TV only. '' '' See GraphicsTest.c for usage example. '' Graphics_Font is the character set in separate GraphicsFont.c file
