 /**
-Stores uniform variables for a shader program.
+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.
