The functional changes are:
* primitives are rectangles, not triangles anymore
* only texture coordinates can be set
* screen coordinates are fixed (the screen is paved with rectangles, all the 
same) and can no longer be freely changed, except for the rectangle size, 
number of rectangles and origin of the upper-left rectangle
* interpolation is done with 6 bits of extra precision (fixed point), which 
are used e.g. for bilinear filtering
* bits of the interpolated texture coordinates can be masked (logic AND), to 
disable filtering, implement wrapping (on texture sizes that are power of 2) 
and maybe other funny effects.
* texture coordinates are 2x32-bit vectors

AFAIK, most or all cases have OpenGL equivalents.

Thanks,
Sébastien
