Fix some issues affecting compositor usage

[WillPower3309]

A few points from the scenefx patch notes on dwl:

NOTE: Some GTK apps are being cut off when they have shadows enabled. You can use the shadow_ignore_list option to prevent shadows from being rendered on those apps

NOTE: Blur doesn't work on windows with opacity set (opacity_active, opacity_inactive)

NOTE: In DWL's Makefile scenefx must be placed before wlroots, e.g. PKGS = scenefx wlroots wayland-server ...

Hi, I'm the author of the scenefx patch

NOTE: Some GTK apps are being cut off when they have shadows enabled. You can use the shadow_ignore_list option to prevent shadows from being rendered on those apps

Regarding the note above, I just wanted to point out that DWL uses wlr_scene_subsurface_tree_set_clip to prevent apps from overflowing their available space, and that the usage of wlr_scene_subsurface_tree_set_clip with scenefx causes some GTK apps to look cut off.

Screenshoots

Here, I used the wlr_scene_subsurface_tree_set_clip function to clip all apps at 250x250

Personally, my guess is that wlr_scene_subsurface_tree_set_clip doesn't work as expected for GTK3 apps that have size hints

BTW, DWL doesn't listen to size hints

Shadow off:


Shadow on:

Does #56 fix this? :)

Hi @WillPower3309, I’ve just tested DWL v0.8 with SceneFX from the latest commit in the main branch (b2e0ac4beb85aa89d0357dc8fcf8762808650890), and I can confirm that the following issue has been resolved:
