Add padding property to background image

[jt-github]

For those of us that like to have a little icon as a background to help remind us of which tab we're in, the backgroundImage, backgroundImageAlignment (I prefer topRight), and backgroundImageStretchMode (I prefer none) are perfect. That sort of thing is usually desirable for images that fill up the whole pane, but smaller images that live somewhere other than the center of the pane are forced to slam up against the edges.

I propose a new property to allow adding a little space between the image and the edges of the pane:
backgroundImagePadding

Thanks for the request! This sounds like a /duplicate of #2620 to me, so I'm gonna close it out. I think this use case would totally be subsumed by offsetX/offsetY 😄

Thanks for the quick action and for finding that this is a duplicate, @DHowett, and yes, the offsets would handle this nicely.
