### Description
Adds per-window screen sharing aka toplevel capture via `ext-foreign-toplevel-image-capture-source-v1` based on the sway implementation <br>
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 <br>
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`).

| --- | --- |
| `wlroots` ≥ 0.20 |  mandatory |
