Well you do have PaintEntity and PaintSurface, the former applying the same brush to all surfaces. So I guess that would make sense.
I haven't tested, but I don't think a brush is automatically created when you use EntityTexture. I think brushes are created when you use the GetBrush commands, and the properties are populated at that point.
