See if we can do something smart to reduce texture sizes

If you are bringing in props to a scene and scaling them down it's often the case that the textures could be quite big despite the objects being relatively small in the scene. It might be worth trying to keep the scene size under some amount and using texture resizing etc to reduce scene size. (We have a 100MB limit right now.)

The issue does not name any files, tests, or entry points. Start by locating the scene import and texture-processing paths, then investigate resizing textures to keep scenes under the stated 100MB limit; done should mean smaller scene sizes without unacceptable visual quality loss.
