Speed up slow pixel limit tests (#404)

Browse Source 
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.
