This is done by checking the number of bitplanes from the image buffer. We assume that for float buffer to use the same bitplanes as it was a byte buffer. Then, the data of the image buffer is packed at the start of the `rect` or `float_rect` before upload. **Statistics - einar.v004.blend ** Note that not all grayscale textures have been stored as BW images so the amount of memory that can be reduced would be more.
