Um, that's not really garbage. It's infinity. The top of the image, representing 90N, is actually one point. The code is trying to find the closest pixel of the original image for that location, and it's finding it, effectively stretching that top row of pixels up to the top of the map frame.
I think you have a point, though, that the code should just use clear pixels for those areas. I've been looking at how to do that, and there doesn't seem to be a good test for it right now for those projection types (LLXY and CADRG).

Routine layers don't have a problem, but the extra space around the earth image had garbage, as shown below (look above 90 deg N) . Any idea how I can get rid. (Beside not creating my frame with this default.) Again, no other layers produce garbage in the border region. openmap.png
