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: Moar state tracking
...
Track what we really need to send for inset shadows, which are used
as a border replacement in many cases.
Fishbowl says I can draw around 200-300 more switches per frame like
this too.

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: 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];

same file.
