Description

Adds per-window screen sharing aka toplevel capture via ext-foreign-toplevel-image-capture-source-v1 based on the sway implementation
XWayland clients work in basic testing but it should be considered rather experimental. There is some possible restacking edge-cases but I was not able to reproduce them yet
Note that the captured surface is rendered a second time into its own scene, so there's a small GPU cost while a capture is active

Targets the dwl wlroots-next branch (base commit d41ecb745c).

Requirements

Requirement Notes
wlroots ≥ 0.20 mandatory
xdg-desktop-portal-wlr ≥ 0.8 chooser_type has to be configured as dmenu
