Do you really need 32bit normalized formats? I thought usually hw can't
really deal with them anyway (because essentially you can't convert to
floats without losing precision).
Some other minor nits inline, can't say if the approach in general makes
sense (might make more sense to support these formats fully?).

Should probably 32bits (and 4 bytes) if it's named R32.
