What? Scale is just in a and d.  And why not just use CGAffineTransformScale?

Doesn’t matter much since b and c will always be zero. But yes I’ll use CGAffineTransformscale here.

You seem to be repeating yourself. Maybe these cases should be ||’d?

Is this what other people usually use? I feel like I’ve seen fancier things.

Probably should.

This should be using the pinch recognizer in the else statement.
