+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.
