better language for Trace Bitmap "stack"
Migrated from: https://bugs.launchpad.net/inkscape/+bug/1692550
Back in the day (say version 0.44 to maybe 0.46 or 0.47) (I'm not sure when the change happened) the Stack Scans option literally meant either stacked or having scans tiled across the canvas.
At some point, Stack became an option for having overlapped colors, while unstacked means having path operations automatically applied to them. And there no longer is any option for tiling the colors across the canvas. The problem with keeping "Stack" as the name for it, is that unstacked still actually looks stacked, unless you know what you're looking for.
I'm suggesting to change the language to "overlapped" or not overlapped.
Thanks for listening.
