bl4nkTHEBUNKER f57b79ef51 fix(libScePad): report the DualSense touchpad resolution

The controller information reported 1920 by 943, the DualShock 4 height with
the DualSense pixel density, while the host controller's fingers were scaled to
1920 by 942 and the keyboard touch contacts sat on the 942 centre line. A title
that maps touch coordinates through the reported resolution lost the lower part
of the touchpad. The width and height now live beside the pad state and all
three places use them.

Unknown function info

scePadUnknown_n3kSX62fgNo (libScePad, NID n3kSX62fgNo) - the name is unknown, and the 0 returned after scePadInit is inferred, not measured. In the OS 10.01 system module the function takes no arguments, returns 0x80920005 before scePadInit, and otherwise sends a per-process value of 1 to ShellCore over Mbus, returning 0x809200ff if that call fails and 0 if it succeeds, with or without an open handle. The #3177 probe measured 0x809200ff in a process that is not a game; a game process is assumed to get 0. The ShellCore setting it changes is unknown and not modelled
scePadSetAngularVelocityDeadbandState (libScePad) - with the deadband on, each angular velocity axis whose magnitude is below 0.017453292 rad/s (1 degree per second) reads as 0, before the orientation is integrated; it starts off. Threshold, per-axis test and default follow duaLib, which reimplements the PC libScePad.dll; the console's threshold is not measured, and the deadband is kept per library rather than per handle since one pad handle exists
scePadOpen and scePadOpenExt (libScePad) - special ports (type 2) return DEVICE_NOT_CONNECTED (0x80920007) because the host has no special controller, and scePadGetHandle has no handle for them; whether the console opens a handle and reports the device as disconnected later is unknown. scePadOpenExt handles only special ports. PPSA01317 passes a 16-byte param that names the device by vendor and product id (b7 0e 04 0e ... for 0x0eb7:0x0e04) and skips the user on any negative result. Other port types throw
scePadVrControllerReadState (libScePad, NID iA-DdobUen8) - the name hashes to the imported NID; the (int handle, void* state) signature follows PS5VR (PPSA99177), which passes a PS VR2 Sense controller handle from scePadOpen type 3 or 4 and a 0x68-byte state it reads as buttons at 0, stick bytes at 4 and a connected byte at 0x40. The title calls it only after sceHmd2Initialize succeeds, which it does not here, so every call throws; the state layout is otherwise unknown
PPSA07411 PS VR2 imports declared without parameters, signatures unknown, added without an implementation because the title fails to load without them: scePadVrControllerSetVibration, scePadVrControllerSetVibrationMode and scePadVrControllerReadCombinedState (libScePad) and sceVrTracker2ResetLocalCoordinate (libSceVrTracker2)
scePadSetVibrationMode (libScePad) - modes 1 to 3 and 5 are accepted and stored. On a PS5 (firmware 13.60) the call returns 0x80920005 before scePadInit, then rejects a mode of 0 or below with INVALID_ARG before it checks the handle, and returns INVALID_HANDLE for a bad handle with any higher mode; whether an open handle accepts modes above 3 was not measured, since the payload could not open a pad; 5 is accepted because PPSA25286 passes it on its open handle at start-up; the meanings of modes 3 and 5 are unknown (PPSA21480 calls it with 3 right after scePadOpen and aborts on failure; SharpProspero names only 1 and 2). The stored mode has no other effect
scePadIsRemoteController (libScePad) - the name hashes to NID fCWdlnmB1Ks; the signature (int handle, bool* remote) comes from PPSA16064, which zeroes a byte, passes its address after scePadGetControllerInformation and ignores the result. The error codes follow the other pad calls. Controllers are local devices, so the answer is always false
scePadSetAngularVelocityBiasCorrectionState (libScePad) - inferred signature (int handle, bool enabled) follows scePadSetTiltCorrectionState and scePadSetAngularVelocityDeadbandState; an invalid handle returns PAD_ERROR_INVALID_HANDLE, disabling is a no-op, and enabling throws because bias correction is not modelled
scePadGetAccessibilityControllerState (libScePad) - the value a console reports for a DualSense is not measured; the emulated pad, which is not an Access controller, reports 0. The name hashes to NID zBsgF0q8DIM. In the OS 10.01 system module the (int handle, uint32_t* state) function returns 0x80920005 before scePadInit, then INVALID_ARG for a NULL state and INVALID_HANDLE for a bad handle, and otherwise asks the pad driver for a per-device value of the device behind the handle: 0 when no device is behind it, 1 when the driver has no answer, else the driver's value. What the values mean is unknown

Functional

Touchpad resolution (libScePad) - the library reports a DualSense to every title, so the controller information reports its touchpad, 1920 by 1080 at 44.86 pixels per cm, and the host controller's fingers and the keyboard touch contacts are placed in that range. duaLib reports these values for a DualSense and 1920 by 943 at 44 for a DualShock 4, and the Linux kernel's hid-playstation holds 1920 by 1080 against 1920 by 942 for the DualShock 4. A DualShock 4 on the host reports through the DualSense range too, so its last touchpad rows are never reached. The console's values are not measured
