Subject: Cleaned up TiledRenderer capable to be used w/ GL2ES3 and
TiledRenderer2 to be used w/ GLAutoDrawable.
- Remove GL2 dependencies
- Only requires PixelStorage ROW_LENGTH -> GL2ES3
- Position target buffer position according to skip [pixels, rows]
- Use an interface PMVMatrixCallback, allowing user to reshape
the custom 'PMV Matrix' according to the current rendered tile
- Properly adjust tile/image buffer to written position and flip for read operation
