hitting this damn shader module again. Very unergonomic interface with the fact that the entry point doesn't just own the shadermodule

Realistically, what should the API for this thing look like...
It's going to just generate a pipeline. But that consists of loading and compiling various shaders,
and generating a pipeline for those shaders and other customer behaviour.
This best works I think if I allow users to
A.) impl from a base trait which allows resource lookup
B.) Generate 1 of each of the types of shaders
C.) Modify specilization constants, whatever that might mean
D.) impl from a base trait which defines it's interface
