Jens Arnold	fa7eb56c84	Greyscale library: * Defer application of lcd linearisation + gamma in buffered mode to the actual update. This simplifies the update function (grey_update() and grey_update_rect() now are just calls to grey_ub_gray_bitmap_part()), and makes DRMODE_COMPLEMENT work properly. * Make the simulator version work and behave more similar to the target version. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16080 a1c6a512-1295-4272-9138-f99709370657	2008-01-13 18:39:09 +00:00
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
