where the new Java 2D TextureRenderer was destroying and re-creating
the OpenGL texture every frame. This was why the Java 2D Overlay class
was so expensive, and why the TextRenderer wasn't as fast as it seemed
it should be. Fixed bugs in all of the Java 2D demos which were
covered up by this implicit sync, as well as in the TextRenderer class
itself where it was missing a key sync operation. Added code to the
Texture.updateSubImage() implementation to clip the incoming rectangle
to the bounds of the input data and texture, to keep OpenGL from
dropping almost-valid updates on the floor. Ran all of the Java 2D
integration demos to verify these fixes.
