With desktop zooming, we need to separate the concepts of "may have a distinct
visual viewport" from "has mobile viewport sizing logic applied to it".
This can be thought of as completing the disentanglement of zooming from meta
viewport support started in bug 1459260.

This is just a super-low-risk work-around for bug 1554755 that we can uplift to
beta, I'll follow-up in a bit in there with a fix and a test.
The reason my patch breaks this is because my patch stopped making images
reframe.
The reframe was of course a very expensive way of invalidating that bit ;)

This should be an idempotent patch. The way to come up with this patch has been:
* Run the first script attached to the bug and pipe it to xclip, then paste it
in color.rs
* Add the relevant #[derive] annotations and remove the color.mako.rs
definition.
* Reorder the values to match the ColorID definition, on which some widget
prefs and caching stuff relies on.
* Manually port some documentation from nsLookAndFeel.h
* Run `rg 'eColorID_' | cut -d : -f 1 | sort | uniq >files`
* Run the second script attached to the bug.
* Manually fix usage of `LAST_COLOR` (adding the `End` variant), and adding
casts to integer as needed.
* Add an static assert so that people remember to update the prefs, rather than
a comment on the definition :)

Currently, `nsISelectionDisplay::DISPLAY_ALL` is used only by `HTMLEditor`.
And only when it's set, `nsImageFrame::ShouldDisplaySelection()` returns `false`
if only its `mContent` is selected. However, this is based on an assumption,
that is, when only one `<img>` is selected in an HTML editor, it's target of
resizers. However, this is completely wrong. Web apps can disable resizers
with `document.execCommand("enableObjectResizing", false, false)` and now,
it's disabled by default.
Therefore, this patch makes the method check whether its `mContent` is
target of resizers at the moment.

We previously (in bug 1491235) adjusted some utility code to make
layout-contained frames behave as if they have no baseline.
But that's not sufficient. To make frames fully report lack-of-a-baseline,
we now do the following for layout-contained frames, as of this patch:
(a) We now leave the ReflowOutput outparam's BlockStartAscent member at its
default value (which is what we do for frames without a baseline like
e.g. nsCheckboxRadioFrame and nsHTMLCanvasFrame). And if the parent cares
about the baseline, it'll then ask directly, using a baseline getter.
(b) We now return 'false' in more implementations of bool-returning
baseline-getter-methods (where 'false' indicates 'no baseline').
(c) We now return the margin-box-bottom edge, in the nscoord-returning
'GetLogicalBaseline()' getter method. (We typically do this by deferring
to the inherited method, which ultimately comes from nsFrame's
implementation). It's appropriate to use the margin-box-bottom edge when
there's no baseline, per the definition of 'vertical-align: baseline',

This will save us some time from figuring out what's the best thing to do in
bug 1552587, so that other patches I have in flight (mainly bug 1552708) can
land, since we cannot add a single byte to nsStyleDisplay right now otherwise.

me that should be easy to bring back should we have an emergency (and I commit

I did this instead of just (ab)using the fact that every list item has at least
one counter-increment node because:
* I don't have the bullet frame around by the time we initially compute the
counter increment, which means that I'd need to grow nsBlockFrame / add a
frame property for the list item ordinal, which I think would be unfortunate.
* It feels more consistent with the way regular CSS counters work and with the
way we want ::marker to eventually work.

In RTL scroll containers, the right most x-axis scroll position is 0 and
leftward scroll positions are negative values. And also
nsLayoutUtils::TransformFrameRectToAncestor, which is used to tell whether the
snap target element is inside the destination snapport or not [1], returns
negative x-axis positions for elements in RTL scroll containers if the element
is positioned at places where the elements are outside of the initial scroll
position (0, 0). So we don't need to tweak snapport postion even in the case
of RTL scroll containers.
Instead, what we needed in the first place is that we choose a proper x-axis
scroll position that the targe element appears inside the snapport.

This enables destructors for tagged unions in cbindgen, implemented in:
* https://github.com/eqrion/cbindgen/pull/333
Which allow us to properly generate a destructor for the cbindgen-generated
StyleBasicShape (which now contains an OwnedSlice).
For now, we still use the glue code to go from Box<BasicShape> to
UniquePtr<BasicShape>. But that will change in the future when we generate even
more stuff and remove all the glue.
I could add support for copy-constructor generation to cbindgen for tagged
enums, but I'm not sure if it'll end up being needed, and copy-constructing
unions in C++ is always very tricky.
