Use background-size, background-position properties to render
CSS gradients.
Some cleanup in display_list_builder.rs related to gradient
calculations.
Adds two wpt tests for tiled gradients.
Note: For now even gradients with background-repeat: no-repeat
are repeated. Sometimes the gradient is not repeated everywhere.
Enable vars-background-shorthand-001.html CSS test.
selectors: Add parsing support for ::slotted().
Without turning it on yet, of course.
The reason why I didn't use the general PseudoElement mechanism is because this
pseudo is a bit of its own thing, and I found easier to make ::selectors know
about it (because you need to jump to the assigned slot) than the other way
around.
Also, we need to support ::slotted(..)::before and such, and supporting multiple
pseudo-elements like that breaks some other invariants around the SelectorMap,
and fixing those would require special-casing slotted a lot more in other parts
of the code.
Let me know if you think otherwise.
I also don't like much the boolean tuple return value, but I plan to do some
cleanup in the area in a bit, so it should go away soon, I'd hope.

Handle cases where selection API doesn't apply
The selection API only applies to certain <input> types:
https://html.spec.whatwg.org/multipage/#do-not-apply
This commit ensures that we handle that correctly.
Some notes:
1. TextControl::set_dom_selection_direction now calls
set_selection_range(), which means that setting selectionDirection will
now fire a selection event, as it should per the spec.
2. There is a test for the firing of the select event in
tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/select-event.html,
however the test did not run due to this syntax error:
(pid:26017) "ERROR:script::dom::bindings::error: Error at http://web-platform.test:8000/html/semantics/forms/textfieldselection/select-event.html:50:11 missing = in const declaration"
This happens due to the us of the "for (const foo of ...)" construct.
Per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of
this should actually work, so it's somewhat unsatisfying to have to
change the test.
3. I removed tests/wpt/web-platform-tests/html/semantics/forms/textfieldselection/selection-not-application-textarea.html
because it doesn't seem to add any extra value - the selection API
always applies to textarea elements, and the API is tested elsewhere.
4. If an `<input>`'s type is unset, it defaults to a text, and the
selection API applies. Also, if an `<input>`'s type is set to an
invalid value, it defaults to a text too. This second case doesn't
currently work, and I'll need to do more restructuring of the code in
a future commit. See discussion with nox in IRC:
