Some controllers show up as both HID and mFI. In that case we probably
want to let the user pick which driver to use, rather than balance
across them.
This fixes issues with the analog stick moving in the wrong direction
on the y axis.
* Enqueue replay record/playback until next frame
This fixes a bug where stdin commands activated via polling would
trigger replay record/playback in the middle of a frame, then input
checking would pull from them before the next frame came around---it
only makes sense to change the active replay in between frames, not
during them.
* fix comment syntax
Add keyboard overlay preset, keyboard submenu, and osk_toggle hotkey. Use overlay caching for osk_toggle.
For now, keyboard menu has only preset path, auto-scale toggle, and opacity.
Related fixes:
- input_keyboard_event: Don't check hotkey binds when device is RETRO_DEVICE_POINTER
- Add input_keymaps_translate_rk_to_ascii() for correct character input to input_keyboard_event
- input_overlay_poll: Delay clearing INPUT_OVERLAY_BLOCKED flag until there is no overlay input (Avoids stray input after osk_toggle)
- Send keyboard events for modifiers before other keys (for correct modifier+key input if hitboxes overlap)
Adds overlay_cache_ptr to keep a disabled overlay in memory when it's expected to be shown again.
Most input_overlay_deinit calls are replaced with input_overlay_unload, which caches the overlay unless initing/deiniting core or disabling overlays.
Loading a cached overlay is done as a swap, intended for osk_toggle.
Related updates:
- Fewer parameters for the overlay loading task. Use current settings when enabling an overlay
- Add input_overlay_check_mouse_cursor() to preserve show/hide mouse behavior
- Don't apply input_overlay_show_mouse_cursor in windowed mode (controlled by mouse grab only)
- Remove some dead code
assignments for strings longer than 2 chars
- Use strlcpy concatenation instead of strlcat
- Make sure that what remains of iteration of the '_len' variable
for manual char assignment
is done in a safer way so mistakes are less possible
