Expected Behavior

rotate(90) should have resulting width===oldHeight and height===oldWidth

Current Behavior

rotate(90) provides a rotated image with incorrect dimensions. Code for the plugin indeed shows it does things like uni-laterally increase the resulting width and height to be an even number, etc.

I assume it is the same for rotate(-90), rotate(180), and rotate(-180)

Probably some special cases could be considered for fast rotate.
