Comment 2 for bug 1375054

@Egmont: I'll let you in on a secret. I was playing around with Cairo, and I have test code that will paint the window background with images. Then we just use the vte3 terminal transparency you came up with when you did the initial port. This will let us fully replicate background image, and much, much more. My plan is to make it generic enough to do "fake background", anchored emblems, text underlay with custom fonts, etc. It should even allow control of scaling, opacity, rotation, blur, and (in theory) even animation. Also the idea is to have a *window* background, and a *terminal* background.

It's not a huge stretch to make elements visible based on criteria such as this request. Of course this relies on me being unemployed so I actually have time to implement it :-D
