Collision Example added

[IonSwitz]

Our 10th Example is now the Collision example.

It illustrates precision Touch events, that is based on the geometry of objects, rather than merely boundingboxes.

It also works as a test benchmark for my new "Stroke vs Stroke" intersection test. This allows precision testing on line level, and will return an impact point for the user. There are improvements that can be made when it comes to speed, but so far, it makes for a quite fun little demo of what our beloved Graphics Extension can pull off.

I have extended Example 10 now to demonstrate how the user can get all the intersection points from a Stroke vs Stroke test.

The various shapes here (three stars, and one shape with an ellipse and a rect) are intersected and the intersection points are displayed as small colored NGon dots:

The dots also remain for 0.5 secods, which is why it looks like there are dots in odd places. In reality, all 4 Strokes rotate continously, creating an almost mesmerizing display of balls and shapes. :)

Nice! Happy to see it in the extension. Though I've done my own test for intersections I'll certainly try this to see what's faster once it get's a little more quiet around here.

The example can run slow because of the large number of NGons that are created as the colored balls. Uncomment that code for proper performance tests

I actually intend to test this with my use case, so I'll simply swap the routines and let two identical devices run our app to see what's what.
Not really a fan of synthetic benchmarks any more, given the very strange results of my tests last week. ;)
