These apis have been renamed a few times, and the docs
haven't kept up.

07fb33c033 gl renderer: Fix private function name
It's a GskGLRenderer, not a GskGLRender

00c6340777 gsk: Add some more shader docs
Do a pass over the docs and address minor inconsistencies,
cosmetics and formatting differences.

Mention GSK_DEBUG=shaders.

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.
