It appears that the calculation for point inside is not correct when the button image dimensions do not match the button size dimensions

[jayson-h]

It appears that the code does not account for image sizes that do not match the button size (probably only applies to development builds as production images should match the button size).

I added the following logic inside of "pointInside" to account for image sizes that do not match the button size (I did not test for Retina Display @2x images). You may be able to design something more elegant.

CGSize iSize = buttonImage.size;
CGSize bSize = self.frame.size;
point.x *= (bSize.width != 0) ? (iSize.width / bSize.width) : 1;
point.y *= (bSize.height != 0) ? (iSize.height / bSize.height) : 1;

Thanks for this. I also received a couple of comments on my blog that my code does not work in all cases. I will try to put some time into this class in the next few weeks.
