To avoid triggering pointer-truncation bugs in applications.

Explicitly enable the few programs that need it.

Whilst uniscribe won't break on the space here (see LB13 of the Unicode
line breaking algorith), DrawText does

Make sure we poll queries before we go to sleep, to e.g. avoid hangs
in Rocket League.

For h264 byte-stream format, we should set "streamheader".
"codec_data" is for avc.

We also set timestamp of the buffer to 0 because
mp4mux will be error if the PTS is none.

Rewrite needs this.

Pointer confinement may only be enabled by the compositor if the pointer
enters the confine region. If the region is small (as in many
mouselook cases) it's very likely that this will never happen and the
pointer will remained unconfined.

To allow mouselook to work more reliably, prefer to lock the pointer if
a window is confined and the cursor is not visible.

When the cursor is hidden and a pointer constraint is active, transition
to relative mouse motion to enable mouselook in 3D games.

Use the zwp_pointer_constraints_v1 protocol to implement cursor
clipping. Note that Wayland only allows us to constrain the cursor
within the extents of a particular target surface.

Borrow the concept of "managed" windows from WineX11 and use it
to decide whether a window should become the foreground window
when receiving the Wayland keyboard focus.

Although 16-bit function names are not case sensitive, it's best to
match the 32-bit version.
