WIP: Transformation of instances in world coordinate space:

Browse Source 
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.
