rendernode: Fix Cairo rendering of repeating gradients
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.
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.
centerlayout: Fix measuring in presence of baselines
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.

testsuite/gsk: add explicit dimensions to <svg> elements
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.

snapshot: Fix push_repeat () with empty child bounds
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.
It's expected that gtk_widget_get_root() will return NULL if the widget
tree does not contain a root widget. I don't know what that means or why
it happens, but it's true in gnome-control-center's network panel when
displaying the OpenVPN configuration dialog. We need to handle it.

tests: Accept slightly different numeric results
FLT_EPSILON is the distance between 1.0 and the next distinct floating
point number, and doesn't necessarily have anything to do with the
precision we can expect from a series of floating-point calculations.
Experimentally, 1e-6 is achievable, even on platforms with unusual
floating point implementations like i387.

be enough to avoid this problem.

gtktexthistory: restore 'modified' flag on redo
When redoing a history entry, its `is_modified` flag is not
reflected to the history state tracker. So GtkTextBuffers may
expose a modified=FALSE status, despite a change was actually
applied to the buffer.
For the undo case, an `is_modified_set` flag was set on the last
entry of the undo queue when a change of the modified state of
the history is requested. This commit does the same on the first
entry of the redo queue.

rendernode, snapshot: Slightly expand color matrix docs
Based on reverse engineering the color node and contrary to my
expectations, the matrix/offset is expressed in, and applied to,
unpremultiplied colors. The colors are being explicitly
unpremultiplied, transformed according to the matrix/offset, and
premultiplied back (see color_matrix.glsl). The matrix is getting
transposed.
Also, copy the same blurb to the corresponding GtkSnapshot function.

The code was appliying the matrices in the wrong order: we have to apply
the inner node's matrix first, and the outer one second. Due to the
matrices being implicitly transposed, the matrix multiplication was done
in the right order, yet the wrong matrix was being mutliplied by the
wrong offset vector.
To make the code a little easier to follow, create explicit variables
for the resulting matrix and offset (instead of reusing matrix2 and
offset2), and fix & expand the comment to document how matrix
transposition factors into this.
