Feature Request: Ability to have multiple views

[celer]

Hi, I'd really love it if I had the ability to have multiple views.

Essentially my process is to set the background image to something I'm trying to model and it would be awesome if I could have an multiple views on the sculpted model so that I can compare it to the images I'm modeling from.

It makes sense, but having multiple 3d views would take a bit of work (UI works and also performance penalty too)
For now I'm only sticking with bug fixes or quick-to-implement features.

@stephomi Hm, could you implement a way to import an image as a textured plane? We could then use the imported images for reference in space. Maybe even deform the image itself.
