Add support for Android P

[DranzerX]

As of API Level API level Build.VERSION_CODES.P only Region.Op.INTERSECT and Region.Op.DIFFERENCE are valid Region.Op parameters.

So I have the next error at Handle.onDraw(Handle.java:101):

I see the problem. It should be fixed in a little over a week as I'm unfortunately abroad at the moment. Anyone who is willing to fix it before me is encouraged to so. The bounding box of the bar and handle needs to be increased without increasing the visual size of the components.
