`layers.clipPath()` does not apply `paintOffset` to `path` correctly when used in `paint()`. about boxy

[pingbird]

This is expected, the paint method has an offset canvas, but it should be restored before pushing new layers since those layers might not actually be drawn to the same canvas as the rest of the widget.

Just to confirm this is what expected, I might have phrased it badly at first.
In BoxyDelegate.paint(), The path argument provided to layers.clipPath doesn't automatically get global offset added.(it's difficult to get the global offset in paint() since BoxyDelegate.paintOffset is being masked.)

However in BoxyDelegate.paintChildren() layers.clipPath does apply the global offset to the path argument.
