Detailed Description

A task for visualizing non-color AOVs such as depth, normals, primId.

Different kernels are used depending on the AOV: Depth: Renormalized from the range [0.0, 1.0] to [min, max] depth to provide better contrast. Normals: Transform each component from [-1.0, 1.0] tp [0.0, 1.0] so that negative components don't appear black. Ids: Integer ids are colorized by multiplying by a large prime and shuffling resulting bits so that neighboring ids are easily distinguishable. Other Aovs: A fallback kernel that transfers the AOV contents into a float texture is used.

This task updates the 'color' entry of the task context with the colorized texture contents.
