Add the PS4 functions sceVideoOutSetBufferAttribute and
sceVideoOutRegisterBuffers on top of the existing registration. The PS4
call uses the first free attribute set and returns its index. It
accepts linear A8R8G8B8_SRGB and A8B8G8R8_SRGB buffers, which map to the
PS5 B8G8R8A8 and R8G8B8A8 formats. It throws for tiled buffers, whose
PS4 layout differs from the PS5 one. Linear PS4 buffers may be 4 KiB
aligned: the OpenOrbis graphics sample places its second 1920x1080
buffer 8,294,400 bytes after the first. PS5 buffers keep the 64 KiB
rule. A handle with PS4 buffers writes the PS4 flip status (64 bytes)
and vblank status (32 bytes). Writing the 128-byte PS5 flip status into
the sample's stack structure overwrote its saved frame pointer.
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.

PPSA02530 (PRAGMATA) fails to load without these imports that no library exports. Their signatures are unknown, so they are declared without parameters and throw until they are implemented. Adds a TechnicalDebt entry.

A frame presented from guest memory with APS5_DUMP_FRAMES is read back
at the size of the display buffer, and that whole copy went into the
dump writer's queue with the scale beside it (31.6 MiB for a 3840x2160
buffer). The queue holds 64 MiB, so the third frame the writer had not
finished ended the run with "frame dump queue exceeded 64 MiB". A frame
blitted from the resident image is already reduced on the GPU and queued
at the reduced size.
The readback is now reduced by the dump scale when the slot retires and
queued at that size, the same pixels the writer kept before. With
APS5_DUMP_SCALE=1 nothing is reduced and the limit is reached as before.
video_out_frame_dump_queue presents four 3840x2160 frames from guest
memory while the writer is held on the first file and compares every
dump with the decoded display buffer.
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.
