Support "screen" (all monitors) capture on wayland. This should be done by getting all drm fds and multiple EGL_DMA_BUF_PLANEX_FD_EXT to create one egl image with all fds combined.

Support pipewire screen capture? Support pipewire screen capture?
Support screen rotation in nvidia wayland. Support screen rotation in amd/intel/nvidia wayland.
Support wlroots dmabuf screen recording, because it doesn't require root access unlike kms grab. Support wlroots dmabuf screen recording, because it doesn't require root access unlike kms grab.
Capture cursor on amd/intel wayland without xwayland.
When nvidia supports hardware cursor then capture the cursor. Right now the cursor is captured because it's a software cursor so it's composed on the dma buf.
