Check on Windows examples (they may be wonky now)

[OliviaLynn]

Would be good to investigate and resolve (or at least document) weird behaviors in Windows examples.

Mentioned in #1:

If you have time, there are some funky aspects to the Windows examples, perhaps due to the latest Windows and OF, but things work well enough for someone who wants to integrate multitouch into their own app to do so.

example-touchCircles - works
example-touchDraw - works but screen sometimes flashes black and paths sometimes glitch out
example-selectionContours - problems
example-imageGestures - works but doesn't display images

If I recall, I think selectionContours never actually worked, but I optimistically kept it in there in the hopes of finally getting it working.

So, it may be the least viable to troubleshoot.
