`assets` template tag should define a variable with image ratio

[efoken]

Expected behaviour

When using image assets, I often need the image ratio, for calculating stuff in JS or whatever. I ended up using {{ width | divide:height }} everywhere in my code, but it would be much easier if the assets tag defines a ratio variable containg the pre-calculated value.

Actual behaviour

It doesn't.
