Crop frame view exports to current video size

Browse Source 
The base video size of the Game Boy core is the Super Game Boy’s resolution of 256×224 pixels.
Previously frames were exported at that size, leading to a 160×144 frame surrounded by uninitialized memory.

This assumes that the base size is always greater or equal to the current video size.
