Anatolii Smolianinov f758cd1115 backend/wayland: Fix HiDPI support for nested compositors ... When running a wlroots-based compositor nested under another Wayland compositor with HiDPI scaling, the nested window appears blurry and incorrectly sized. This is because the Wayland backend does not: 1. Detect and track the parent compositor's output scale 2. Set wl_surface_set_buffer_scale() to match the parent's scale 3. Multiply output dimensions by the scale factor when handling configure events This patch fixes all three issues by: - Adding wlr_wl_parent_output structure to track parent outputs - Listening to wl_output.scale events from the parent compositor - Setting buffer_scale on all backend surfaces (output and layers) - Scaling output dimensions to account for buffer scale - Setting wlr_output.scale so nested clients render at correct DPI Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/854		2025-10-30 11:13:32 +01:00
