4229a37e90 arc: Fix the derivative 
Scale the derivative such that computing the arc length
of a unit quarter circle wil produce the expected result
of PI/2.

4ab03e79b7 Drop some unnecessary code 
We tell path_foreach to split into lines or cubics,
so no point in having code to handle quads and arcs.

d33ed4f9ab path: Add elliptical arcs 
Add a new curve type for elliptical arcs
and use it for rounded rectangles and circles.
We use the 'E' command to represent elliptical
arcs in serialized paths.

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.

8634d67cff Some fixes for gsk_path_builder_add_segment 
We must be careful with single-point contours
that contain just a move. These never occur in
practice, but our randomized tests produce them
regularly.

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.

823cb714ec introspection: Remove 'caller-allocates' from POD types 
The (out caller-allocates) and (out callee-allocates) annotations are
meant for structured or pointer types. Plain old data types are just
regular out parameters and don't need the annotation about who allocates
them.
