gsk: Use clip defines in shaders
...
Use the NO_CLIP and RECT_CLIP defines to make
simpler shaders for these cases.
Note: This does not work yet.

glsl: tweak pre-processor to support Apple GLSL compiler
...
The Apple GLSL compiler cannot deal with empty pre-processor blocks such as
#if GSK_GLES
#elif GSK_LEGACY

gl: Add some namespacing to the preamble symbols
...
This adds a gsk prefix to the stuff in the preamble, as we want to
avoid it conflicting with things in the main shader. Especially once
we start allow some customization of shaders.

gl renderer: Transform rounded rect on the GPU
...
Change the RoundedRect struct we use in our shaders so we can transform
it using (affine) matrices.

gl renderer: Add some in/out compat glue to the shaders

so we can use _IN_ and _OUT_ and get the right things for
desktop/es/legacy GL.

gl renderer: Make RoundedRect work in gles
...
Which can't return struct types containing arrays. So let's revert to
the previous version but still send the rect along as a vec4[3];

gl renderer: Rewrite shader builder
...
Use a unified approach to write both vertex and fragment shader in the
same file.
