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.)
