> I'm concerned about the performance implications of this simple loop. Seems like you could fall into this slow tiling when you have a small background image with tiling over a large div (say a 1x1 px image with a 1px space over a 1000x1000 div).

That slow path is there just to help graphics libraries that do not have native support to render patterns with padding (eg. Skia, Cairo). CoreGraphics can draw patterns with different spacing, so I will add the fast path in a different patch/bug. 

Another solution might be to compute an image in memory with the size of the tile+padding and draw that using the native library.
