It's all in the matrix.

You will want to read
http://www.xaraxtreme.org/developers/documentation/co-ordinate_system.html
and 
http://www.xaraxtreme.org/developers/documentation/the_camelot_rendering_system.html

as background reading. The translation is fixed point in the sense that
all coordinates are fixed point. I can't off the top of my head remember
where the fixed point is in practice though - from memory there is
a define in gconsts.h or similar. Perhaps Luke can help.
