Textures.

This is increasingly showing its origin as a quick afternoon hack with
more and more bolted on, but let's see how long I can avoid actually

Comments for fun
Janky panning
And zooming!

Complete with breaking things out so the crosshair stays constant despite
your zoom level;
Throw another GroupLayer into the mix!

Strictly speaking, things COULD call Layout on the Shim again,
which could do exciting things, blahblahblah. Of course all this
is playing super fast and loose with mixing TP elements and
flump bits just drawing on their own Layers, but...
Crack out zoom functions.

I'll be wiring mousewheel to it, so...
Hooray. Can stick a fork in that hackery
