fixed an issue with the AbstractImageHelper image cache that it didn't dispose of the textures properly and glg2d would run out of video memory
extended the testing to more realistic framerate and anti-aliasing showing glg2d blowing away Java2d
removed the animator from the GLG2DCanvas and made it easier to add one if it's wanted
FontMetrics should take into account kerning, so just pawn off the layout to the Font
do not use fractional metrics (not sure when to use them)
