The source uniform may or may not point
to a glyph atlas. The optimization we do
for color nodes is only possible if it does,
so check this.
Fixes: #6094
This function is deprecated, but we should still document it properly.
It appends, not prepends. This is clear enough from its implementation,
but also we have practical experience with WebKit in:
https://github.com/WebKit/WebKit/pull/8663
Matthias prefers to avoid the prepend, append, start, and end
terminology altogether.
Cairo and the GL renderer have a different idea of how to handle
transitioning of colors outside the defined range.
Consider these stops:
black 50%, white 50%
What color is at 0%?
Cairo would transition between the last and first stop, ie it'd do a
white-to-black transition and end up at rgb(0.5,0.5,0.5) at 0%.
GL would behave as it would for non-repeating gradients and use black
for the range [0%..50%] and white for [50%..100%].
The web would rescale the range so the first stop would be at 0% and
the last stop would be at 100%, so this gradient would be illegal.
Considering that it's possible for code to transition between the
different behaviors by adding explicit stops at 0%/100%, I could choose
any method.
So I chose the simplest one, which is what the GL renderer does and
which treats repeating and non-repeating gradients the same.
Tests attached.
If the entry has icons, we may end up increasing our minimum and natural
height compared to the values the text child returned. In that case, we
should also adjust the baseline values to account for the text being
shifted down.

The measure logic (unlike the allocation logic) was enforcing strict
baseline alignment of child widgets even if no child widget had valign
set to baseline. This was causing GtkCenterLayout to request more size
than it actually needed.
Instead, bring the logic closer to that of GtkBoxLayout by introducing
explicit have_baseline and align_baseline variables. We track and report
baseline if have_baseline gets set, but it only affects our reported
minimum and natural sizes if align_baseline ends up set, which happens
if there's a child widget that has valign set to either one of the two
baseline values, and itself reports a valid baseline.

The compose table stores the keyvals to match against
in a guint16 array, so it can't handle directly encoded
Unicode codepoints (which have a high bit set). Warn
if we encounter those.
We require folks to include gskglrenderer.h in order
to create a GL renderer. So we be careful to only
include header in gskglrenderer.h that won't trigger
ugly warnings.

Without an explicit width, height, and viewBox, there is no single
correct way to render an SVG. In the absense of said information,
librsvg is capable of making a guess by rendering the SVG to a Cairo
surface and then analyzing that surface; however, this process is
merely heuristic.
There are three GTK tests for SVG images that are missing dimensions.
While this is not a violation of the SVG specification, it does
implicitly couple the test to the librsvg rendering heuristic. In this
commit we add that dimension information so that the expected result
is unambiguous.
...and not around the center of the render node, as one could expect
given that the render node syntax for rotation, transform: rotate(90);,
happens to match the CSS syntax for the same thing, and CSS does rotate
around the center by default.

The logic would confuse empty child bounds (in which case nothing should
get rendered) with NULL child bounds (in which case the child node's own
bounds should get used). In fact, if the child bounds are empty, we can
discard the descendant render nodes completely, getting a nice little
optimization.
