A 16 bit color texture format that only has a red channel.
The value of the red channel will be in the 0..1 range. Currently, this texture format is only useful for native code plugins as there is no support for texture importing or pixel access for this format. R16 is implemented for Direct3D 9, Direct3D 11, and Xbox One.
Note that not all graphics cards support all texture formats, use SystemInfo.SupportsTextureFormat to check.
