Updated the View2D class.
Fixed fixed width font rendering bug in BitmapFont2D.
tiny optimization in 'QuadBatch.addQuad'.
Optimized Render2D transformation matrix generation.
Fixed bug where vertexID was being used instead of zero.
getBounds() function would not work when specifying numVertices that is
smaller or equal to vertexID. This was because vertexId was being used
incorrectly in the for loops. Zero should have been used instead.
Improved StatsMonitor/s FPS dispay to act more calmly and not jump over
max. fps.
