All uses of the old target scale API actually wanted to disallow scaling of the mouse cursor. This commit adapts our API to this and thus simplifies backend implementations. Some backends, most notable the Wii and Android, did some implementation of the cursor target scale, which I didn't adapt yet. I added a TODO for the porters there.
