Several things are accomplished in this commit, including: - Use OIIO instead of our own functions for pixel format conversions (cleaner code/less for us to maintain) - Fold all PixelService functions into the PixelFormat class (cleaner code) - Moved OpenGL pixel definitions to OpenGL classes and out of the global classes. - Add support for RGB buffers as well as RGBA (optimization)
