Engine v4.4.1

A patch to Solid.

• Savi places things on top of anything now — models, primitives, sprites, custom geometry, or text, she knows the size and lands the placement first try.
• Custom uploaded models that disappeared after the animation migration are back — your characters keep their model and animations switch correctly.
• Non-square images render on walls and floors again — photos, screenshots, and posters no longer come out as blank white spots.
