iAudio M3: Optimised LCD driver, with more/better assembly code. Speedup is ~80% when boosted, ~15% when unboosted. Also implemented grey phase blitting. * Adapted the greyscale library, and the plugins using it. * Fixed a bug in greyscale scroll down for vertically packed pixels.

Cabbiev2 gigabeat background: reduce WPS backdrop filesize by storing it as 24 bit BMP instead of unnecessary 32 bit.

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.

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.

Greyscale library: * Introduced some extra macros dealing with block size, allowing to write some parts with less #ifdefing. * Optimised grey_update_rect() for horizontally packed LCDs, and unbuffered scrolling.

Greyscale library: Changed the internal data format once more (separated pixel values and phases), allowing for further optimisation of drawing, scrolling etc. * Optimised grey phase blitting in the core reduces CPU load on all architectures, most significantly on coldfire. Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing.

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.
