1. On devices less than xhdpi request a 1x image from MapTiler (such devices are generally old, slower and with little memory so avoiding to get the 2x image only to have to shrink it later could help).
2. Coerce too big width/height combos within the API limits keeping the aspect ratio (this will allow requests on big horizontal displays to succeed).
3. Don't crash when given weird width/height combos (i.e. zero or negative).
4. Introduce interfaces to hide this whole logic and make it easier for forks to implement their own.
