CustomBadge crashes when used in FXBlurView

[paul-piro]

i get this error when used with FXBlurView in iOS 7

Assertion failed: (CGFloatIsValid(x) && CGFloatIsValid(y)), function void CGPathAddArc(CGMutablePathRef, const CGAffineTransform *, CGFloat, CGFloat, CGFloat, CGFloat, CGFloat, bool), file Paths/CGPath.cc, line 279.

so i added the following condition in drawRoundedWithContext
if(rect.size.width > 0 && rect.size.height > 0) {
}

only then we allow the code to be executed else the app will crash
