The Swift version of SKTUtils gives many compilation errors on OS X about sktutils

This seems to be a 64 bit v 32 bit issue.

CGFloat is typealiased to Float. However, Float is always 32 bits, whereas CGFloat is meant to be 64 bits on 64 bit hardware.

We may need to use CGFloat until Apple figures out just how broken their code is.

For some reason, the compiler on OS X is more strict about its types. On iOS this works fine:
extension CGPoint {
init(angle: Float) {
return self.init(x: cosf(angle), y: sinf(angle))
}

But on OS X it needs to be written as:
extension CGPoint {
init(angle: Float) {
return self.init(x: CGFloat(cosf(CFloat(angle))), y: CGFloat(sinf(CFloat(angle))))
}

Maybe this is a different build setting, maybe it's a compiler feature/bug. Let's wait until we get a new beta.
Maybe we should also use CGFloat in the API instead of Swift's own Float.

Resolved by renaming all uses of Float to CGFloat.
