Add auto fire option for virtual joypad

[simontoens]

I would like to be able to easily enable and disable auto fire when using the virtual joypad. This should also work when connecting remote virtual joypads.

That would be nice. Question is how to add this:

First: Should this be only for Button Mapped to Joypad input or just for some buttons or should this apply to all buttons.
Second: How to do this in a user friendly manner

My first Idea is this:

For devices supporting force touch it would be a option to use this for auto fire. For devices not using force touch a twofinger tap or a swipe on the button could do the trick. I think the button should also be in another color when autofire is activated.

I like the force touch part but I'm not very happy with the not force touch part. Alternative would be a small button on the bottom left or right depending on where the joypadbuttons are active to turn it on or off completely.

I think it is enough to only add it for the fire button, not for all buttons the joypad exposes.

To enable/disable, it could be a 2 finger swipe anywhere across the screen. There would have to be some visual indication that it auto-fire is currently enabled - for example a small red square could show up on the top left corner if auto-fire is enabled.

Or to rephrase, if auto-fire can only be triggered for a single, pre-determined button on the virtual joypad, that would be enough for 99% of games.
