Captured photo is larger than preview

[jrleeman]

When the PiBooth takes a photo, the saved image is larger than the preview on screen. In one way this is nice because it insures that nobody has their head/arm accidentally cutoff. It is problematic when working on a small backdrop though. It appears to be an upstream issue with the camera preview. You can set the system up to use the video port, but the image quality degrades. You can also crop the image before saving/tweeting. I chose not to do that as I'd rather have a image that needs cropping later than to have a forever too-cropped image. There is a discussion of how to do this (a couple lines) on the original issue. For now, we'll mark this upstream and leave it. I suppose if there is strong opposition to this behavior we can add a cropping option. waveform80/picamera#23
