While the slowdown of the ISR is minimal (the intermediate buffers are in IRAM), the planar grayscale buffer takes only half the space for a given depth, and gray_update[_rect]() and unbuffered drawing/scrolling are faster because less data needs to be moved. It should also make porting of video.rock somewhat easier. * Archos recorders, Ondios: Some slight optimisations of the grayscale library. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7571 a1c6a512-1295-4272-9138-f99709370657

\| \| \| \| \| \|	the intended 49-shade mode isn't possible due to interference between the internal greylevel generation of the LCD and external pixel flipping, so the lib allows 33 shades as on the Archos. The current implementation wastes RAM by not switching the LCD to b&w mode and simply using colours 0 and 3 only. However, this allows to show a partial greyscale overlay and normal 4-shade graphics in parallel. (2) Converted all asm blocks to use symbolic parameters. (3) Properly marked asm input parameters that are changed within the block as in-out and feed them from a temp variable where necessary. (4) Screenshot is not yet working on H1x0. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7244 a1c6a512-1295-4272-9138-f99709370657
*	Complete rework of the grayscale library: (1) Implemented the new rockbox ↵	Jens Arnold	2005-07-25
	graphics api. (2) Added buffered mode, and implemented most drawing functions for buffered mode only. Buffered mode will ease implementation of animated graphics. Some functions are additionally provided as unbuffered versions (drawing grayscale bitmaps, scrolling) since unbuffered mode is better suited for non-animated graphics (JPEG viewer, mandelbrot) and saves some RAM, which is important on Archos. (3) Put all functions in a couple of source files, no more one-function-per-files. This became possible since sectioned compilation for the plugin library and appropriate linking for the pluginswas introduced, otherwise the binaries would be bloated by unused functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@7241 a1c6a512-1295-4272-9138-f99709370657
