Add touch swap functionality and support for 2.5x resized screen mode

[cnux9]

Add “Resized_2_5x” Screen Mode: top screen 2.5× on left, bottom screen scaled on right.

New setting: tap top-right corner to swap the two screens.

Fix touch bug where taps outside bottom screen repeated the last touch.

I wanna try it, you should put a vpk in the 'releases' page of your fork. Screen swap might be need a different hotkeys if someone adds a fullscreen or near-fullscreen mode like 'mystery dungeon mode' at the bottom of 'issues'.

Thanks for the comment. I've added .vpk to my fork.
I'm also working on a pip mode with full screen on the left and margin on the right (the small pip screen will be here and slightly overlapping). So I think it might not be too bad.
I'll try it out in different ways and try to add the option you mentioned (select + start maybe?). Touch swap is my preference because I don't like holding multiple buttons and accidentally affecting the game.

2.5x has a lot of stretch artifacts. You can REALLY see it in the charizard's eyes and the 'top screen' minimap. Try this vpk (not the same as Schluss's current version), I think this scale might look better for your touchswap. Its X scale is 3 and Y is 2.8333333, and the mini screen 1 to 1. Your 'fixing' of the touchscreen does cause an issue with games like Modern Warfare 3 where when your touch comes back into bounds, it clicks whatever was at the edge but normal DSVita works good. It might work good to leave front touch alone and try remapping screenswap to "L2/R2" (google Vita cases with L2/R2 and you'll know what I mean. It's certain spots at the back touchscreen that the PS1 emulator likes)

It'd probably be best to be ultra-conservative about button combinations and not add them unless totally necessary in case a game needs them or a later DSVita feature needs them or until things are more planned out. I could imagine select+up and select+down being used for something else such as transparency on the mini screen and maybe select+left to put the bottom screen left, and select+right to put the bottom screen right or something.
