Add display zoom feature

[genos1213]

It would be nice if you could zoom in like the PS2 emulator. I think it's better than stretching the image since you don't get any distortion and most games don't have useful stuff on the very edges of the screen anyway so it's a more natural wide-screen.

It can also make text a bit bigger, which will potentially be an issue trying to play the latest console games on mobile which tend to have tiny text.

Games on the edge have health bars, mini-maps, indicators, etc.

They don't on the very edge, there's a spacing away from the edges normally. On PS2 you can often zoom in 10% without losing any of the ui.
