553499522c contour: Add measure API 
In order to compute path lengths efficiently, we need
to cache lookup tables. This commit adds API to let
contours allocate and free such measure data, as well
as API to use the data to go length -> point and
vice versa.

ae7ec40cf2 rendernodeparser: Generate better default child 
... for fill and stroke nodes.

It's most likely we want the path bounds (or path stroke bounds),
so make the parser use those by default.

eec90d1026 pathbuilder: Add rel-variants for arc-to 
Add rel-variants for all our arc-to APIs. This is
a pretty harmless addition, and it is more consistent
to have these for all ..._to functions.

d07a6b8566 snapshot, gsktransform: Mention that rotation happens around (0, 0) 
...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.

5bc82f4141 Change curve derivative api 
We don't need to have the derivative as a curve,
it is enough for us to compute values of the
derivative at a given t, which we can also do
for conics.

25e6231a88 path: Switch back to conics 
Arcs were appealing, but they have a fatal flaw: we can't
split our arcs without changing the ellipse they trace.
That could be fixed by adding an extra parameter, but then
it is no longer any better than conics.

So switch back to conics, which have the advantage that they
are used elsewhere.

d665d2fb89 vulkan: Add nonuniformEXT() where needed 
The magical term to know about (because the GLSL compiler or the
validation layers sure as hell don't) is:

  "dynamically uniform expression"

because if you don't have that when indexing a texture or buffer array,
you need to add nonuniformEXT() around the index variable.

Fixes the close icon on AMD having glitches of the previous icon visible
in some pixels.

246a7cfeab 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.
