We chose 8 renderbuffer because it seems to be commonly supported on mobile gpu and is more than 6 which is needed for generating cubemaps. 4 was the minimum guaranteed by ES3.0. The main changes here are: - TargetBufferFlags is now a uint32_t instead of uint8_t - The number of render buffer supported by filament and supported by the hardware can now be different. Applications/users now must query this value if more than 4 is needed. - added a backend query (used gl terminology) This is a redo of a previous attempt. There was an issue in the GL backend that caused MRT to fail on some devices.
