This should address the second point of #4502.
A few notes:
1. it changes the current behaviour of the 'Fullscreen cursor'. Currently it defaults to be captive. This changes it so that it defaults to NOT being captive, but can be made captive with the CTRL+L key combination.
2. There are situations when in windowed mode it's possible to escape the captivity (it's like a minigame if you will). This requires the mouse movement to exceed the bounds of the window in a single event scan. It will just show up as a temporary visibility of the cursor when outside of the window bounds. It's not too difficult to 'fix', but might not be a likely enough scenario to warrant either.
3. There currently isn't an ability to change what this keyboard combo maps to, but it's inline with a collection of other similar keyboard mappings. I think adding such a more generic keyboard mapping system (not for just keypad items, but system items.. e.g. so that Emulator stop could be mapped to something other than CTRL+S etc) is a bit out-of-scope of this particular PR.
This is just some workaround until we either use a different input api for keyboards or until we refactor the keyboard_pad_handler to use Qt with native scan codes
Adds new lerp factors to the keyboard pad handler In order to simulate triggers and analog buttons.
See "Analog Button Lerp Factor" and "Trigger Lerp Factor" in the yml in InputConfigs/Keyboard/.
Values Range from 0-100 as before, where 100 is instant press and 0 is never.
Currently I'm not planning any GUI element for this.
