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