* RGBA format with 10-bit components packed in 64-bit per pixel, with 6 bits
* of unused padding per component:
Add 1, 2, 3, and 4 component 32b float formats, so that buffers with these formats can be imported/exported with fourcc+modifier, and/or created by gbm. These correspond to PIPE_FORMAT_{R32,R32G32,R32G32B32,R32G32B32A32}_FLOAT in mesa.
