Detailed Description

One shader's precompiled binary data for the on-disk cache.

Stores the GL program binary for a fragment or compute shader, plus an FNV-1a hash of the source file so stale entries are detected on load. Fragment entries can contain both 2D and 3D variants; compute entries use binary_2d for their standalone program and use a 3D passthrough slot.
