fix bug 141, ellipse hang on drawing

[yodalee]

I think the problem is that
in resizeTouched the State variable will be set to -1 because of <= comparison
change to < will solve the issue.

It is now crashing on OSX Mavericks, with:

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

Part of the crash report:
