Button background gradient

[nmrsmn]

I would like to see the option to add gradients (Brush) to buttons for backgrounds..

Currently it is possible to do, with a "workaround": If you set (or let) the background color to be Unspecified and add a modifier with a call to .background() that contains the brush and the shape (in case you need rounded corners) it works, but I think it should be obtained in the API to either set the backgroundColor or provide a backgroundBrush
