| | | | | | | | | | | | | | | * api change - all drawing functions now use draw mode, foreground and background shades set globally by separate functions * There are now 4 draw modes for all drawing functions, no more separate functions for inverse drawing * Significant speedup of 1-bit bitmap (and font) drawing (2..3 times) * Some more speed tweaks * Additional functions for horizontal and vertical lines * Copied describing comments to the header file for easier reference * The safety net against an uninitialized grayscale buffer is gone git-svn-id: svn://svn.rockbox.org/rockbox/trunk@4711 a1c6a512-1295-4272-9138-f99709370657
