AI created changes, should it create PR's or work on my own fork

I am actually not sure if the already existing shaders would break if i pass a vec4 tex coordinate. (Which is perfectly valid). I am alwasy talking custom shaders here obviously. Currently the buffer type, aka name is not bound to an actual type. And only InstanceData is allowed to have more then 4 components. (It is a mat4 in the case of instancing)
