Issue #1495 showed that the docs of GtkGrid retain outdated implications
that (as was once, but is no longer, the case) it is intended to replace
GtkBox, by discussing HfW and widget properties in a way that suggests
GtkBox can't handle them. But of course it does, and it's preferable for
simple single-row/column cases. Worse, we said GtkGrid “provides exactly
the same functionality” for the latter case, but the original point of
that Issues was that it doesn’t, at least for CSS positional selectors!
Box:
• Use an actually meaningful @Short_description.
• Remove unhelpful @See_also references to unrelated containers.
• Remove references to “rectangular area”: it might be another shape
via CSS, or “rectangular” might falsely imply 2 dimensions of children.
• Mention Orientable:orientation.
• Emphasise usefulness of :[hv]align for allocating in the other axis.
• Don’t say that Grid “provides exactly the same functionality” for a
single row or column, since (A) it is overkill for that case and (B)
said Issue proved that it *doesn’t* for CSS child order, for example.
Grid:
• Don’t dwell on widget properties and height-for-width in a way that
wrongly implies that Box can’t handle those (or Grid can better). In
fact, just get rid of that bit altogether: Box handles them fine, and
such wording was only needed years ago for migration from GTK+ 2 to 3.
• Point to GtkBox as being preferred for the simple row/column use case.
As per the spec:
> The back buffer can
> either be reported as invalid (has an age of 0) or it may be
> reported to contain the contents from n frames prior to the

So a buffer age of 1 means that the buffer was used in the last frame.
We were handling buffer_age==1 the same as buffer_age==0, i.e. we
returned the full damage for the surface.

Append a variation selector to the Emoji sequences,
to force Emoji presentation. Without this, some
Emoji come out with text presentation by default.

- step back on toning down the borders. Flatness !> legibility.
- darker active state for light
- draw gradinets from bottom up, to keep px sized shading regardless
of button size.
Instead of getting the translation x/y everytime we use the modelview,
get it once, when extracting the metadata. Do the same with the scale.
And save if the matrix is "simple" at all, i.e. if it only consists of a
translation and/or scale. This will be helpful later when we start
drawing transformed nodes on textures.
