Bug 496280

SUMMARY
Spectacle takes time (that I believe to be longer than it should be) to take a high resolution screenshot (eg. a large region on a 1440p/4K display or between two 1080p displays).

STEPS TO REPRODUCE
1. Invoke the rectangular region screenshotter
2. Take a screenshot of a large area (preferably >1080p)

OBSERVED RESULT
More than 500 milliseconds are needed to close the region selector copy the screenshot to clipboard

EXPECTED RESULT
It should probably take less time (see specs below for reference)
