Probably need to special case our default asset creation to create an appropriately shaped rectangle instead of a square.

Sample code:

import ppb


class Platform(ppb.RectangleSprite):
    pass


def setup(scene):
    scene.add(Platform(width=3, height=1, position=ppb.Vector(0, -5)))

We end up with a square of size 3 instead of a rectangle with a 3:1 aspect ratio.

What it should look like:

Noting, this currently gets set in the asset (https://github.com/ppb/pursuedpybear/blob/canon/ppb/systems/renderer.py#L93-L107) and would require some refactoring to make it possible to contextually choose the asset definition.
