Okay -- so a box over a box IS in fact the best choice when it comes to casting things like syntax highlighting. I will come back to this and explain more, but a prominent example which this will be based on is the password box here, which uses a similar technique with images.
So these now exist, but I need to get the highlighting working properly in order for the effect to be complete, + bind this to spacebar keyup in the key-map.
