Criteria for a good selection algorithm:
1. If there is an exact fit, use it
2. If all candidates have the same aspect ratio, use the best fit
- prefer slight downscaling over slight upscaling
- prefer slight upscaling over large downscaling
3. If aspect ratio of candidates differ, use the best fit
- For all subsets of (approximately) same aspect ratio, (2.) should select
one candidate per set
- Determine which of the subsets yielded the best overall candidate
The last point is difficult to answer - prefer upscaling a candidate with
matching aspect ratio, or downscaling a nonmatching one.
