A Vulkan surface can offer HDR10 formats while the display is not in
HDR (KDE Wayland with RADV lists them with the output's HDR disabled),
so on hosts other than Windows the probe now reports an SDR monitor and
HDR output stays off until an output-state signal exists. A probe test
checks that a window without a Windows monitor report reads as SDR with
an HDR10 surface.
The HDR10 present test now also changes the monitor's luminance while
presenting HDR10, and the presenter logs the HDR metadata it sets.
AI-assisted: yes
Detect HDR output on the host: on Windows the monitor showing the window
must run in HDR10 (DXGI IDXGIOutput6), and on every host the window's
Vulkan surface must offer a 10-bit VK_COLOR_SPACE_HDR10_ST2084_EXT
swapchain with VK_EXT_swapchain_colorspace and VK_EXT_hdr_metadata. The
monitor's luminance comes from DXGI; hosts that report none get 1000
nits peak and full frame, 0 nits black.
While HDR output is available, sceVideoOutGetOutputStatus reports
dynamic range 2 and flag bit 0, sceSystemServiceGetHdrToneMapLuminance
reports the monitor's luminance, and every open port's output mode
event fires when that changes. PQ display buffers are presented
unchanged through an HDR10 swapchain with HDR metadata; any other
display buffer switches back to the SDR swapchain. Without HDR output
the PQ to SDR conversion uses the peak the title was last told as its
white level.

Build SDL's Wayland backend next to X11 and ask SDL for "wayland,x11"
on Linux, so the window runs natively under a Wayland compositor instead
of through XWayland. SDL loads libwayland, xkbcommon and libdecor at run
time, so systems without them, or sessions without WAYLAND_DISPLAY, keep
using X11. SDL_VIDEODRIVER still overrides the choice.

Writes the 80-byte status described in #2746: the sceVideoOutGetOutputStatus
fields followed by zeros, with the documented codes for a null status and an
unknown handle.

The console's mouse reports relative motion, so the host cursor can never line
up with the cursor a title draws. While a title has a mouse open and the
window is focused the host cursor is hidden and captured, released on focus
loss or while the pad's mouse-to-stick toggle is on. Motion deltas are scaled
from the presented image's size in window units to the title's display
resolution with sub-pixel carry, so the title's cursor travels as far as the
host pointer would, on scaled desktops and letterboxed windows alike.

The NID -q-vbO859Tw, declared as sceVideoOutUnknown_q_vbO859Tw for
PPSA02530, hashes to sceVideoOutDeleteVrrActiveStatusEvent. It removes the
handle's VRR status registration from the queue like the other Delete*Event
calls, the counterpart of sceVideoOutAddVrrActiveStatusEvent.

Registering a flip or vblank event on a handle that sceVideoOutOpen never
created, or that was closed, threw, which ended titles that register
their flip event before they open the port and ignore the result. The
documented error SCE_VIDEO_OUT_ERROR_INVALID_HANDLE is returned instead,
the same check sceVideoOutSetFlipRate and the other output calls use.
The flip test program gains an "unopened" mode.
anyps5-input.ini accepts LeftStickDeadzone and RightStickDeadzone (whole
percent, 0 to 90), a radial deadzone on the controller sticks whose
remaining travel is rescaled to the full range, and MouseSensitivity
(above 0, at most 10), which replaces the fixed factor of 1 for mouse
look. The defaults keep the current mapping exactly.
sceVideoOutSubmitChangeBufferAttribute2 threw when a buffer of the group
had a flip pending, and Marvel's Wolverine makes that call with flips in
the queue. A flip now takes its buffer group when it is reserved, in
submission order, so flips submitted before the change keep the
attributes their buffers were rendered with and later flips use the
new ones.

Elden Ring Nightreign (PPSA25380) imports the function, which no library
exported, so the title failed to load. The option is ORed into the buffer
attribute and a null attribute throws. Options other than 0 and 8 still
throw when the buffers are registered.
libkernel.prx does not export TimedWait::*, so libSceVideoOut.prx had an
unresolved import and titles stopped at load. Compile TimedWait.cpp into
libSceVideoOut, and use NotifyAll for the notify added on main.
The flip queue's condition variable went through winpthreads, whose
timed waits end on GetTickCount64 steps: the present thread's 10 ms poll
for SDL events and the pad, taken while no flip is queued, ended 11 to
24 ms later on Windows, and WaitForFlipRoom's 60 s bound had the same
granularity. Use TimedWait::Condition, which waits on an event and a
high-resolution timer, so the poll ends at 10 ms and a submitted flip
still wakes the present thread at once.

Unsubscribe an event queue from the output mode events that
sceVideoOutAddOutputModeEvent registers, the same way the flip and
vblank events are removed. Deleting a registration that does not exist
succeeds, and a null queue or an invalid handle throws.

sceVideoOutVrrPegToFixedRate and sceVideoOutVrrUnpegFromFixedRate were
NotImplemented without arguments. Both take the output handle; the peg
also takes two further arguments whose meaning is unknown. VRR is not
modelled and the output always runs at a fixed rate, so both validate
the handle and return 0; non-zero peg arguments throw. Recorded in
TechnicalDebt.
Uncharted: Legacy of Thieves Collection (PPSA05684) stops on main with
"sceVideoOutVrrUnpegFromFixedRate not implemented"; it passes its
output handle to both (and zeros to the peg) and ignores the results.
A flip packet names a buffer index; the buffer was looked up when the
command buffer was submitted, so a title that registers its buffers
after submitting the first frame failed with "flip buffer is not
registered". The buffer is now resolved when the GPU reaches the flip,
as the hardware does. A flip whose buffer is still unregistered then
presents black and completes (see TechnicalDebt).
Uncharted: Legacy of Thieves Collection (PPSA05684) submits its first flip before registering its buffers and stopped with "flip buffer is not registered".
A title that opens a main and an overlay port flips both, and every flip
was presented as a whole frame, so the window alternated between the two
buses: PPSA01736 shows its intro on the main bus and an empty overlay,
and the intro blinked black on every other frame. Overlay flips now
complete and signal their events without being shown. Compositing the
overlay over the main output is not implemented.

Measured on a PS5 (firmware 13.60) through dlopen of
libSceVideoOut.sprx on a handle the payload opened.
sceVideoOutInitializeOutputOptions writes 0xFF to byte 2 of the 64-byte
options and returns INVALID_ADDRESS for a null pointer.
sceVideoOutIsOutputSupported checks the handle, then the reserved
arguments, then the mode, then the options. It never answers 0: a mode
the display lacks returns UNSUPPORTED_OUTPUT_MODE, and a value that is
not a mode returns 0x8029001E. Options must keep the initialized words,
except word 3.

The named VRR functions hash to LibwuIonIBw and kP2L8t3j-aM already.
Their explicit aliases therefore create second PE exports with the same
patched NIDs and prevent Windows builds from completing.
Keep the named function exports and remove their redundant aliases.
The NID patcher's duplicate-export validation remains unchanged.
