Apple Pencil support

[vaporstack]

Hey, it would be great to have pencil support integrated into the main branch at some point. I still use HyperCard for lifedrawing. I implemented detection in my fork, https://github.com/vaporstack/minivmac4ios

but it is a limited implementation. Basically all I do is check the bluetooth stack for a pencil, (PencilDetector.c from SO) and if it's present, ignore all non pencil touches, which most users probably don't want (but I do!)

However I couldn't figure out how to add a user toggle for it. I think this is a highly specific feature that should probably be opt-in either via settings or a pop up dialog box (or both).

Many thanks for your excellent work. :)

I should specify that I'm not ignoring all touches on the app level - just in TouchScreen.m. The other gestures and stuff work fine :3

This sounds great, can't wait to borrow some hardware to try it :)
Maybe if there's a pencil detected, there could be a third mouse option "Pencil only" that enables this behaviour?

That's exactly what I was thinking. The values that I provided probably need a bit of tweaking as well, I noticed a little bit of glitchiness while drawing with it last night.

If it's OK I'll take a look at this.

I have an iPad Pro with Pencil and a desire for it to ignore my palm!

If there's no problem, I'll file a PR soon.
