		fclemUnsubmitted Not Done Inline Actions This function looks weird. I preferred the way it was before with additional parameters to `DRW_mesh_batch_cache_get_edituv_faces_stretch_angle`. Here this function seems really hacky but I agree the other way is not optimal either as you have to know when to dereference the pointer. fclem: This function looks weird.
