As long as the context_priority extension is available request a high
priority context, to help the compositor look fluid despite heavy GPU usage
from other applications at a regular priority.
This becomes sort of pointless if/when unredirection applies, should still
help with overview/workspace switch animations, or if the application is
not fullscreen.
Based on a similar patch by Daniel Stone to Weston.
This is a GAppLaunchContext subclass meant to replace usage of
GdkAppLaunchContext in gnome-shell.
Launch contexts get created from the MetaStartupNotification as
they are closely related. The messaging underneath depends on
the availability of a X11 display, if there is one we go through
it (and libsn). If there is none, we still create startup sequences
manually for wayland clients.
A NULL argument is expected here in order to unset the selection,
meta_wayland_data_device_set_primary() accepts a NULL source, but
gtk_primary_selection_device.set_selection was not handling a
NULL wl_resource.
screen-cast-monitor-stream-src: Only send cursor bitmap when it changes
To avoid unnecessary pixel copying, only send the cursor bitmap when it
changes. This also allows the receiver to know when the cursor bitmap
actually changed.
screen-cast: Add 'cursor-mode' to allow decoupled cursor updates
The 'cursor-mode', which currently is limited to RecordMonitor(), allows
the user to either do screen casts where the cursor is hidden, embedded
in the framebuffer, or sent as PipeWire stream metadata.
The latter allows the user to get cursor updates sent, including the
cursor sprite, without requiring a stage paint each frame. Currently
this is done by using the cursor sprite texture, and either reading
directly from, or drawing to an offscreen framebuffer which is read from
instead, in case the texture is scaled.
cursor-renderer: Add API to allow inhibiting HW cursor
There may be reasons to temporarly inhibit the HW cursor under certain
circumstances. Allow adding such inhibitations by adding API to the
cursor renderer to allow API users to add generic inhibitors with
whatever logic is deemed necessary.
