* Common interface for classes that need to go through the shader generation path

|

* In particular, this includes the shader code generator (ShaderCode).
|
||||
* A different class (ShaderUid) can be used to uniquely identify each ShaderCode object.
|
||||
* More interesting things can be done with this, e.g. ShaderConstantProfile checks what shader constants are being used. This can be used to optimize buffer management.
|
||||
* If the class does not use one or more of these methods (e.g. Uid class does not need code), the method will be defined as a no-op by the base class, and the call
|
||||
* should be optimized out. The reason for this implementation is so that shader selection/generation can be done in two passes, with only a cache lookup being
