Replace raster image gradients (before base64 embedded) for modern
browsers by CSS gradients. Only relying on conventional image URLs
in browsers that don't support linear-gradient.
Also updating color to Wikimedia Design Style Guide color and
removing obsolete *-ltr/*-rtl images that have been introduced in
MW core 1.16.0beta1 but have been replaced by unified 'portal-break'
image afterwards.

Have been in since before Idfc38503d8397ffe where 'portal-break.png'
was still applied on `div.portal` and not ever after on `.portal .body`.

Has been added in 8db5779682, but there's no `span` as direct child
of the watchstar `a` (any more).

Also going with `--modifier` naming scheme when direct pseudo-class
modifying variable. And fixing small typo.

Navigation is the appropriate, general term – settling on it and
unifying file name and common abbreviation 'nav' for variable names.
Change-Id: I237b56320544de15e3b97c4806f6e2387bc54ca0
Unifying variable naming to property-identifier-modifier scheme and
use already existing variables out of mediawiki.ui variables file,
which gets imported by Vector and its variables (like
`@border-width-base`) are already in use in a few places.
Change-Id: Ic25b1517bf180a9bce437215c1309bb9f4dd15be
Unifying variable naming to property-identifier-modifier scheme.
Also removing `@padding` variable with only one single usage, instead of
extracting it from its place of application enable simpler readability.
Change-Id: I602fe645b233000bcecaeee6cf19d20e49a64c78
Unifying variable naming to property-identifier-modifier scheme.
Settling on non-em-based `line-height` values with one exception
of Vector tabs, where removing `em` would lead to different
calculation.
Also removing unneeded `inherit` assignment on content paragraphs
that has been part since Ic5ba836364.

Print-only variables should belong only to print stylesheet.
Also clarifying usage and naming throughout file.

* page-fade:
Remove redundant 'background-image' PNG fallback for
IE6-8 in '#mw-page-base' because the vertical-gradient() already
creates a solid fallback color which seems good enough for IE6-8.
Remove the 'background-color' rule which was only there to fill
the gap above the the IE6-8 PNG image fallback, which in turn
overrode the background-color rule from vertical-gradient.
The background-repeat rule is also redundant with background-image
gone.
* watch-icon-loading:
This is only used when the JS code is active and the user
clicks the watch star. It does not need a PNG fallback, as it
is only needed in Grade A browsers where the JS executes,
which are expected to support SVG.
Also removed the embedding as the rendering of article text
on page load should not be delayed by an icon that might
be used if and when the user clicks on the watchstar (and
irrelevant to logged-out users).

Unifying variable naming to property-identifier-modifier scheme, while
also collecting all non-print values variables in corresponding file.
We will amend the `em` based values to calculations that will enable
rendered full pixel values and also fix some connected
usability issues in the future.

Reyling only on base font family variables. It's debatable if
something like `@font-family-base` would make sense, but with only
3 variables the abstraction would seem over-engineered for the time being.
Change-Id: I294ef8753dd3c73f4ed3fd89d43978dfaf6e0f06
Merging similar value applications in generalized variables,
and aligning to property-identifier-modifier scheme.

Increasing the distance of the button slightly changes the position
from end, putting the icon in a more appropriate place (harmonized
whitespace of input value and icon).
Also simplifying `font-size` calculations readability and equalling
their values in search input and button.

Reducing specificity, simplifying output and merging `padding`
in one place into one shorthand attribute.

The debounce is trailing, not leading/throttled. This means
the value doesn't decide how often it runs while the user is
resizing. It decides how long after they stop resizing will
it first run.
Given the calculation isn't super expensive, a much lower value
should suffice. The main thing we want is that while the user
is actively resizing and 100s of events are queued up (faster than
JS can process), that we wait until the end of the chain before
computing it (once). If the user actually stops moving, even for
a little bit, that little bit however small should be more than
long enough for a repaint to take place.
Test Plan:
* Open two tabs, one after checking out master, and
one after checking out this patch. Make sure you are logged-in
on MW as an administrator user (to get more tabs).
* Verify that `mw.loader.getVersion('skins.vector.js')` returns
different values from the console for each.
* Resize the window from wide to very narrow and back.
Before, the tab bar updates relatively late it feels sluggish.
After, the tab bar appears to update as/while you let go.

requestAnimationFrame (rAF) is called before styles are computed.
Performing a style read there can require a forced style
recalcution which interrupts the browser's natural rendering
life cycle.
To gracefully observe layout of the page without inducing the
cost to render it, it should be accessed after rendering.
A suitable API to schedule time there is requestIdleCallback.
In any event, if the code that needs this measurement executes
very early for some reason, it is still computed on-demand which
means it can't cause any functional regression.
