It now includes direct surface manipulations for pixel and line drawing on DirectX surfaces (16bit surfaces). Even if you aren't interested in rotating polygons, you may want to look at the code just to see how direct surface manipulations are done. There is a good pixel plotting function and an interpretation of Bres's Line Drawing function.
Pasting a texture to the polygon at this point should be a walk in the park. I'll repost an example as soon as I sit down and work it out.
