Subject: Diagnose prop tinting: log prop materials and studio draw model names

Log the first crate materials the tint pass modifies and the first DrawModel/
DrawModelArray calls with their model names, to see whether the crates are
brush materials that were never reached, materials loaded after the tint was
applied, or a studio draw path that is still missed.
