Feature suggestion: crop image

[LunaMoo]

Manually selecting needed resolution should not be a problem, eventually I will add another feature for that. I made a separate display editor screen so I have extra space to add some related options without cluttering graphics settings menu.

I pretty much finished basic screen for it already with working touch control(well I admit tested only with rodent;p), but still needs lots of work to look nice, no clue when I will finish it since this weekend I might be too busy with offline stuff.
