... by rendering the elements as transparent. They are still
there and work, so you can still resize, but you still get a
better view of your UI.
We still draw a border around the UI, just to show where
it ends and the background begins, but that is purely
decorative :-)
I am not totally happy wioth this: It still sets mouse cursors
in the area that should actually be controlled by the UI and
overlays its own touchareas around the border of the UI, stealing
a few pixels from the interactive area of the UI.
And use that in the lsp/ui implementation instead of comments.
This is only a parser support for now, the name is otherwise unused.
Hence I rather keep that experimental.
