1a40e10933 H1x0: Changed lcd_blit() and the grayscale library to use the same internal format as on archos (1bpp). 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.

0c29589d8a Assembler optimised 64 bit multiplication for coldfire: ~15% speedup. Proper max_iter decrease amount.

3d73790ab7 Heavily improved mandelbrot plugin: (1) Calculation now uses 64bit fixed point arithmetics to allow zooming in way further before the precision barrier will hit. Added asm-optimised 64bit multiplication routine for SH1; more than twice as fast as what gcc produces. (2) Precision is dynamically selected based on the zoom level, low zoom factors still use 32bit for speed. (3) Maximum number of iterations is adapted to the zoom level. You can still increase / decrease it while staying at a zoom level. (4) Panning only recalculates the scrolled-in part of the screen -> way faster panning.

773c28e489 Mandelbrot plugin fixes: (1) Aspect handling was broken, it has to keep the x/y aspect which has almost nothing to do with the LCD aspect. (2) Comment about the # of shades. (3) Fixed and tweaked initial x and y limits. (4) Long policy, minor optimisations.

a14f545ded Adjusted mandelbrot plugin to H1x0: (1) Working button assignment. (2) Different LCD aspect. Note that there is something wrong with the aspect when zooming; this was in fact there before, also on archos. (3) Grayscale library init for variable LCD resolution.

c20a00ef3e Complete rework of the grayscale library: (1) Implemented the new rockbox 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.

e35a658ded Plugin rework 2: (all) Compile-time keyboard configuration, for Ondio adaption. (all) Now using the default event handler, standard placement is now in switch() default case. (minesweeper,pong,snake,snake2) added USB handling. (mandelbrot,mosaique) Fixed return value. (minesweeper) fast moving with button repeat. (oscillograph) Fixed cleanup in USB case.
