Moved to consistently use ImageMagick and fixed image scaling regression

Merge remote-tracking branch 'origin/master' into dev/compare.different.sizes

Updating documentation

Forgot to save-dev rimraf

Added expected diffs for different size cases

Updated comments

Adding back Math.max logi

Updating TODO

Moved to transparent border and everything is looking glorious

New resize commands are looking good

Moving to imagemagick

Moving to exclusvely imagemagick

Asserting diff image exists on disk

Catching regression by loading image

Successfully catching error message we were encountering

Added regression test for what we want

It looks like resize actually does an image resize as opposed to a canvas resize (1x7000 scales to 1x7)

Debugging with gm manually. It looks like there is a vertical limit of 6720px

Re-enabling cleanup

Successfully reproducing error with actual images

Attempting to catch regression but failing

Moving to .only for regression catching

Added assertion for different size images

Adding rimraf for clean test assertions

Added assertion for same image diff

Adding comments

Moving to DRY-er image tests
