* Dithering:

* TRUEEMU_M_DITHER_0 : Don't dither if possible.
* TRUEEMU_M_DITHER_2 : Use a two pixel dither if possible.
* TRUEEMU_M_DITHER_4 : Use a four pixel dither if possible.

* -- -o oo -- -- -o -o oo
*
* Palette:
*
* TRUEEMU_M_RGB : Use a whole number of bits for red, green and
* blue. For an 8 bit mode, this is 3:3:2. For
* a 4 bit mode, this is 1:2:1.
* TRUEEMU_M_CUBE : Use the same number of reds, greens and
* blues. For an 8 bit mode, this is 6x6x6.
* TRUEEMU_M_PASTEL : Use a shaded pastel scheme.
