The alias is left there temporarilly and will be removed completely in a later commit where
also components/style/gecko/generated/structs_{debug|release}.rs are re-generated (they still
use the old alias).
Right now when calling getComputedStyle with an element from another document,
we return the style using the pres context of that document, not of the document
of the window getComputedStyle was called on, so this holds.
But it will stop holding if we ever change this, so assert it doesn't happen.

Zoom changes can change the meaning of ems, so we can't re-evaluate media
queries with the old values, because otherwise we may miss a restyle.

This makes the code cleaner, and also documents the fact that effective_rules
recurses into imports.
No we're not adding the imported stylesheets twice, and we share code with the
invalidation analysis.

This is needed for both bug 1357461 and bug 1273303, where I plan to add smarter
invalidations than what we have now.
Also, it's cleaner.
Ideally I'll move this onto stylist, though that may require extra work to make
it work fine for Servo, so for now let's just do the obvious thing.
Now that cascade() gets a Device, we can use the default computed values from
there to avoid propagating that state all over the place.

Ideally this would be lazy, but eventually we're going to need to restyle in
RebuildAllStyleData anyway, which would require us to have the style up to date,
so no need to complicate our lives.

The setup is quite different to Servo-land, so add a comment about the different
setup.
Also, check viewport rules when flushing stylesheets. I believe that the
previous behavior is plain wrong, though I haven't taken the time to come up
with a test case.
In any case, it doesn't hurt any of both back-ends.
