7d261a147d Ensure scaling factors are calculated independently #452 
Fixes bug introduced in v0.15.0 where, if the shrink operation
rounded up along one dimension, it could then also round up the
reduce operation on the same axis, creating a small stretch effect.

1b7c5816fc Speed up slow pixel limit tests (#404) 
This replaces the single color 20000x14000 PNG with a 20000x14000
Grayscale JPG. On a Broadwell Core i7 @ 3.1 GHz this speeds up the
"Disabling limit works" test from ~6.2s to ~0.15s because it can use
jpeg resize-on-load optimizations.

This should fix occasional timeouts on Travis CI.
