Hardware acceleration doesn't work with SDK >= 28

Hey @florent37,

First of all, thank you for your library.

When I used a RoundRectView with a mapView inside it's works fine except for device on Android P and Android Q. I think you just need to check if the canvas is hardware accelerated and set setLayerType(View.LAYER_TYPE_HARDWARE, null) before drawing it (ShapeOfView.java line 154).

Can you fix it?

Regards,
