Detailed Description

Computes the largest-magnitude velocity in the tile with corner at gl_FragCoord.xy * maxBlurRadius.

Invoked from MotionBlur::computeTileMax().

This is run twice, once in each dimension. It transposes the output from the input, so it doesn't need to know which pass number it is in.
