If you can render the texture to the screen in your application
then you can read back the framebuffer to get hardware
acceleration in texture drawing operations. See Hans Kohling
Pedersen's SIGGRAPH papers on texturing implicit surfaces from a
few years back. If you need offscreen updates of the texture, you
are probably best off doing software rasterization into a
java.nio Buffer, at least until pbuffers have widespread support.
