Jens Arnold	a72499a125	Greyscale library: Plugins can now put the management structure in IRAM for higher update speed. Use this in doom, mpegplayer, and zxbox. Made the api pointer part of the struct. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16066 a1c6a512-1295-4272-9138-f99709370657	2008-01-13 00:11:43 +00:00
Jens Arnold	feb5b15e9b	All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15998 a1c6a512-1295-4272-9138-f99709370657	2008-01-04 23:42:38 +00:00
