Pre-Populate GPU Cache

This pre-populates the GPU program disk cache. Pre-population is optional, but once done, this allows subsequent GPU renders start faster. The cache is stored on disk, but if the NVIDIA driver is updated, or the GPU hardware configuration changed, the cache may be stale and need to be re-populated.

Note that pre-populating the cache may take 15 minutes or more to run.
