Same thoughts here. :) But I've some fear about onscreen coordinates. In
SDL pixel coords are very comfortable. I know OpenGL know this feature
too, but you must set up glViewport() and glOrtho() for this to keep
your sprites size correct.

Orthogonal matrices. Yuck! I had linear algebra two years ago (in the
first semester), but I don't like it much despite of that is heavily
used in computer graphics.
