RFE: getModelSpace*() override DAT input for phong MAT

Wishlist and RFEs

Often I just want to change these two functions
getModelSpaceVertex()
getModelSpaceNormal()
in the vertex shader, and it’s a little bit of a hassle to export the shader, change those functions, change other parameters, re-export the shader …

So it would be great if the phong MAT had a DAT input that internally replaces those functions with those defined in the input, so there’s no need for exporting the shader … thx

actually this would only be really usefull if we could also define some custom samplers and uniforms. Guess that makes it a lot more difficult …
