#7 Allow bigger screen recording and other ratios

[Patrick Mosby]

Currently the maximum resolution for screen recordings is 640 x 480 which in my opinion is too small and doesn't respect the aspect ratio of wide screen displays, which results in skewed screen recordings.

It would be great if we were able to a) record the screen with a higher resolution and b) set the ratio to something like 16:10 for MacBook displays.

Thanks in advance
