WIP: Transformation of instances in world coordinate space:
Ulocking the "anisotropic" scaling checkbox will bake the transformation into meshes to allow for scaling in world axes. Optimized and templated the stl_transform functions, now also available for 3x3 matrices. The Canvas3D::reload_scene() now maintains selection even if all volumes of an instance changed their IDs.
