TextRenderer class; displays dynamically rotated, translated and
colored text. Changed how setSmoothing() is handled by the
TextureRenderer and stopped disabling smoothing in the TextRenderer.
For the time being, not exposing this flag in that class to keep the
API simple. Changed TextRenderer to also push/pop the texture matrix.

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.

team, added a TextRenderer class which enables high-performance
rendering of bitmapped Java 2D fonts, with full Unicode support, into
arbitrary OpenGL drawables using a simple API. Builds on top of the
TextureRenderer class and its associated functionality; added
createAlphaOnlyRenderer() and other methods to enable the TextRenderer.
Caches rendering results on a string-by-string basis in an OpenGL
texture using a fully automatic least-recently-used algorithm for good
efficiency when rendering the same string or strings multiple times.
Uses a rectangle packing algorithm, currently housed in
com.sun.opengl.impl.packrect, for managing the positions of cached
strings on a larger OpenGL texture to avoid OpenGL pipeline state
changes. Added a TestTextRenderer demo which simply adds a moving text
string and frames-per-second counter to the Gears demo; more
sophisticated examples to come. (Some commented-out debugging code is
being temporarily left in the new demo, to be removed in the next
checkin, in order to have it in the version history.)

dropped the prefixes on the suggestion of Chris Campbell. No other
changes to these classes. Added com.sun.opengl.util.j2d to the javadoc
generation. Updated demos.
