In the previous implementation, we'd store transform data (Center, CovA and CovB) in 3 x float4 textures (9 values using 12 slots)
Now we store them in 2 x float4 and 1 x float1 textures, so a 25% storage / bandwidth reduction
this is the case for both HALF and FLOAT texture types

On my Mac M1 this has only slight performance improvement (3.8ms -> 3.7ms) but this could be a larger win on more bandwidth limited devices (mobile).
