In -drawRect: I want to check if the provided rect intersects with anotherRect.
I'm not good at this geometry math stuff and especially at english so what I want to say is:
If you have two sheets of paper on the desk, and one of them covers the other either completely or just a small portion, it is rectsIntersect = YES.
How to check that out for rect
