0b2ac4b427 BMP loader: Using shifts for division by powers of 2 saves a bit on code size.

adc4848772 Complete rework of the BMP loader: * Support for 4 bit, 15/16 bit and 32 bit BMPs in addition to the already supported 1 bit, 8 bit and 24 bit formats. * Better protection against corrupt BMP files. * Added dithering for 2 bit targets. * Optimised, compact code. There's almost no code size increase for SH1 (only 68 bytes), and even a decrease for coldfire, with all the additional features. * Code policed. * Fixes bug that loading a backdrop worked only once per session.

e0710b2af1 More color adjustments. Better translation to and from native colors with even distribution of levels. Macros for extracting native depth components and packing them.

fa0ea19d5a Fixed the problem with the backdrops on iPod. The same problem was in the updated color picker and that is fixed too.

76a6aaa278 Added dithering for 24 bit backdrops on 16 bit displays. FORMAT_DITHER should be specified to dither a bitmap when loading. Feel free to flame me if I got the RGB565SWAPPED thing wrong.

effect as the open() takes the longest time).

previously. Made readshort() and readlong() static.
