libgo2 improvements - Expose rga scale mode as param for future use - Cleanup whitespace - Add option to disable managed surfaces and allow direct posting to drm driver oga graphics driver - Uses direct framebuffers in libgo2 - Bitmap font only supported for now - Uses built-in bicubic filtering: graphics quality better than gl + bilinear - Support for rotation
