19 too_many_uniforms(const std::string &w): std::runtime_error(w) { }
20 virtual ~too_many_uniforms() throw() { }
30 Stores uniform values for shader programs.
32 The uniforms are stored in a program-independent way, and UniformBlocks are
33 created to match the uniform layouts of different programs. If multiple
34 programs have the same layout, the same block is used for them.
36 The class is optimized for an access pattern where the set of uniforms and
37 programs stays constants, with only the values changing.
