91472b2ecd gl renderer: Compute final color in vertex shader
This is a very often used shader. No need to to do this for every
fragment.

fdce30d3f8 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.

1243174e53 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];

Use a two-pass blur shader, fix a few other things and unify the
blurring of blur nodes and blurred outset shadow nodes.

a2518493a2 gl renderer: Fix color matrix shader
We *just* computed a un-premultiplied color, maybe we should also use
it.

4869013a8d gl renderer: Fix coloring shader
We *just* pre-multiplied u_color but then didn't use its rgb values.
This fixes backdrop scale marks in Adwaita to not be white.

eaf899061a gl renderer: Remove shadow program
