-Stores uniform variables for shader programs. The uniforms are stored in a
-program-independent way, and UniformBlocks are created to match the uniform
-layouts of different programs. If multiple programs have the same layout, the
-same block is used for them.
-
-The class is optimized for an access pattern where the set of uniforms and
-programs stays constants, with only the values changing.
