I want to reproduce the coloring of the menu bar on the #Mac.
So it seems I need to generate an image where each #pixel-column is the averaged color of that column's pixels (original image being the #desktopBackground).
I thought I'd just create an #NSImage of height 1, draw the desktop picture into it, squishing it vertically. But of course on Retina I get 2 pixels for 1 point.
Anyone remember how to create (and draw into!) an NSImage of height 1px?
