Ben Clayton 03de0e83ae Move tint::transform::Robustness to a santizier transform 
There's no good reason for this to be public.
Move it into the writers, and expose a 'disable_robustness' option to
turn it off. This can be expanded to hold more fine-grain control in the
future.

Ben Clayton be367b73ae Reduce shader complexity for external textures 
Do more math on the CPU to avoid per-fragment ALU operations.
Use a mat3x2 instead of mat2x3 to avoid padding.
