Function mirrorpatch

Reflect one set of patched uniforms onto another shader with the same underlying set of uniforms. This is important for ensuring patched vertex and fragment shaders have the same layout. This is because some transformations occur based off what instructions appear, so as a result, the vertex and fragment shader may have a different layout after a set of transformations
