The common pixel formats on x86 are:
- Palettized 4-bit planar (bigendian, i.e. MSB to the left)
- Palettized 8-bit packed (one byte per pixel)
- 16-bit RGB555 (16-bit littleendian words with R=14:10, G=9:5, B=4:0)
- 16-bit RGB565 (16-bit littleendian words with R=15:11, G=10:5, B=4:0)
- 24-bit RGB888 in littleendian order (first byte in memory is B,
second is G, third is R)
- 32-bit ARGB8888 (first byte in memory is B, second G, third R, fourth
unused in the framebuffer proper)
- 32-bit RGB10:10:10 (I *believe* 32-bit littleendian words with
R=29:20, G=19:10, B=9:0)
