Context stack bug.

[BarakRL]

in DLRadioButton drawIconWithSelection:
UIGraphicsPopContext();
should be called after:
UIGraphicsEndImageContext();
not before.

@BarakRL thx for submitting the bug. Do you know what's the actual impact of this bug?

[BarakRL]

It will corrupt the graphic context stack for the entire app. For example: if you try to create a new graphics context, draw to it and get the image, it will fail and return nil.
