[Openexr-devel] double matrices

[Jonathan Litt]

Speaking of types ...

Anyone else agree that m44d and m33d would be welcome attribute types? (v2d and 
v3d couldn't hurt either.) Floats have too little precision for camera 
transforms in larger-scale scenes, not to mention that many 3D apps use doubles 
universally for transforms, and there's already a double scalar attribute 
anyway. One can work around it with strings, or a series of scalars, but it 
would be great if down the road double were directly available.
