We should support storing grayscale images more efficiently.
Currently we only support image with RGBA colors. For grayscale images, we only use 25% of the memory. We probably should introduce fake ImageData for grayscale images that are mapped to proper RGBA images if required.

Since it is not possible to declare grayscale images with XML3D (the Web only understands RGBA), we will only have grayscale images as internal type.
