psx_host_set_input_sink: an overlay provider sees host SDL events first, in the event drain and the host pause loop, and may consume them. psx_host_set_ui_capture: while on, local game input reads released and centred (netplay included, so peers receive "nothing pressed") and the external-input gate stays closed. Debug builds gain host_key, which pushes a real SDL key event for scripted runs. Inert without a provider. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

/* Ordered external-input resolution for one offline player's pad.
|
|
*
|
|
* (1) physical/local capture -> buttons, device presence; host extras
|
|
* of the port (gamepad present, LT/RT values)
|
|
* (2) offline controller source (psx_mod_set_controller_source), if any:
|
|
* buttons = source & physical; sticks/type from the source, through
|
|
* the controller presentation policy (hook)
|
|
* (2b) title pad transform (psx_mod_set_pad_transform), if any: sees the
|
|
* pad of (1)/(2) plus the host extras (a digital pad with no source
|
|
* as its host pad: real sticks, no stick->D-pad fold); may rewrite
|
|
* buttons, sticks and the presented type (NeGcon packed as PsxNetPad
|
|
* documents). Declining delivers the stock pad of (1)/(2).
|
|
* (3) local mouse policy (psx_mod_set_local_mouse_policy), P1 only: may
|
|
* override ONLY the right analog axes of whatever (1)-(2b) produced;
|
|
* a NeGcon result has no right stick, so it resets the mouse.
|
|
*
|
|
* Precedence: a source never suppresses the mouse policy. The mouse sees the
|
|
* RESOLVED pad (final buttons, final analog flag, final right stick), so a
|
|
* capture is never taken and then discarded, and an active source whose right
|
|
* stick is deflected, whose pad is digital, or whose Start is held disables
|
|
* the mouse exactly as a physical stick/digital pad/Start would. The mouse
|
|
* is reset (capture released) on a released/declined frame, no device, or an
|
|
* armed savestate input guard.
|
|
*
|
|
* Pure: every side effect goes through PadExtHooks, so the order is testable
|
|
* without SDL/SIO. Main (emulation) thread only. */
