Support for uniform structures in GLSL

[Cheemsandfriends]

"Structs are defined much like C++ (note: the C-style typedef struct *{} syntax is not supported). GLSL does not support anonymous structures (ie: structs without a type name), and structs must have at least one member declaration. Structs cannot be defined within another struct, but one struct can use another previously defined struct as a member." More Information.

Structs could be used to organise better your shader code, since this acts as a class without addable functions, letting you make several instances of that code without having a cluttered uniform variable instancing.
