6a972e0249 Finally - grayscale library support for the simulators. Currently SDL only, win32 and x11 won't link anymore due to missing simulator functions.

e49cade42d Colour targets: Adapted mandelbrot plugin. The plugin library now contains scrolling routines for >= 8 bpp displays.

a36b1d4083 New plugin loader. Solves the crashes introduced with the .bss changes while keeping the small binary size. The model & api version check is now part of the plugin loader. Codecs are not yet adapted, but the old method still works for them. Simulator plugins are not (yet) version-checked. API version numbering restarted, as this is an all-new system. Uses the target ID from configure, so don't change that too often.

69ffcd5356 Mandelbrot plugin: New fixed point routines, loosing a tiny bit of precision (3 bits), but way faster than before. Full precision routine uses the EMAC on coldfire. No more 64 bit arithmetics used except within the asm inlines.

cfb073c452 Coldfire: New timer handling on CPU frequency change, adjusting the prescaler on the fly, for both tick and user timer. Precondition is that the higher frequencies are integer multiples of the base: now NORMAL is 45 MHz and MAX is 124 MHz. Removes the need for applications with longer timer periods (>= 10 ms) to boost the CPU all the time, e.g. the grayscale lib. Timer counts are now always based on the base frequency (CPU_FREQ). * Adjusted the RAM refresh timers to the new frequencies (all frequencies for H100) * All: Fixed the tick timer count being off by one.

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.

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.
