GUACAMOLE-187: Reduce cost of layer resize.
This change reduces the overall cost of resizing a layer by:
1. Resizing only in 64-pixel increments, relying on the containing `<div>`
to clip to the requested size.
2. Performing the full save/restore of image state only if there actually
*is* image state to save (resizing a brand new layer is expensive otherwise).
