a9c616284a gsk: Move from g_memdup() to g_memdup2()
The g_memdup() function is replaced by a safer version in newer versions
of GLib.

161ddcfa92 gsk: make render node getters const
This also removes the return if fail macros from these as a good portion
of them didn't have them anyway. I think it's fair to say that access to
these incorrectly is a programmer error.

It significantly reduces the amount of code generated into generally a
movss,ret.

0d2ea14ac1 types: fix various use of volatile in type registration
The use of volatile was incorrect in GLib and has been that way for
a long time. Recently however that has changed, and this makes GTK
follow suit to avoid using volatile in the type registration.

Combined with the above merge request for GLib, this fixes a large
number of compilation warnings when using Clang.

7ea755e206 Add GskGLShaderNode and GskGLShader
A GskGLShader is an abstraction of a GLSL fragment shader that
can produce pixel values given inputs:
 * N (currently max 4) textures
 * Current arguments for the shader uniform
Uniform types are: float,(u)int,bool,vec234)
There is also a builder for the uniform arguments which are
passed around as immutable GBytes in the built form.

A GskGLShaderNode is a render node that renders a GskGLShader inside a
specified rectangular bounds. It renders its child nodes as textures
and passes those as texture arguments to the shader. You also pass it
a uniform arguments object.

2fa9dddea6 gsk: Remember border node uniformity
Lots of border nodes have all the same width and the same color.
Renderers might be able to simplifty that, so keep an extra bit per

3f0a830f3c Properly annotate the render node constructors
Now that the GskRenderNode subclasses are recognised as proper
sub-types, we can annotate the constructors with their type. The C API
remains the same.

e0323fcdc2 Add get_type() functions for GskRenderNode subclasses
The introspection scanner tries to match a type name with a get_type()
function, in order to correctly identify a type as a class.

If the function is not available, we have two choices:

 - add some special case inside the introspection scanner, similar to
   how GParamSpec subclasses are handled in GObject
 - add a simple get_type() function

The latter is the simplest approach, and we don't need to change that
much, since we still register all render nodes at once.

d701a89281 Turn GskRenderNode into a derivable type
Language bindings—especially ones based on introspection—cannot deal
with custom type hiearchies. Luckily for us, GType has a derivable type
with low overhead: GTypeInstance.

By turning GskRenderNode into a GTypeInstance, and creating derived
types for each class of node, we can provide an introspectable API to
our non-C API consumers, with no functional change to the C API itself.

f0993fc881 rendernode: Avoid rounding errors
Compute the pattern matrix directly instead of transforming the cairo_t.

This ensures that when node_size / texture_size is some obscure floating
point value, we don't get rounding issues from scaling by it once we
draw the texture_size rectangle.

I have no actual failure where this comes in handy, but I had written
the code anyway, so decided to keep it.

b12a6be9d9 rendernode: draw() only in node bounds
We currently disable when draw()ing nodes using the cairo fallback path,
which means we can't just use cairo_paint(). Use a proper rectangle
instead.
