32edf29c0a GskGLRenderer: Add debug groups 
This adds debug groups in various places, including the debug
nodes if those are in use. This makes the traces in tools like
renderdoc much easier to read.

e13d242320 gl renderer: Keep op builder around 
GL keeps the unoform state per-program, but not per-frame. So, we can't
pretend that this works for us. Keep the RenderOpBuilder around for the
entire lifetime of the renderer instead.

91bbe6ef95 gl renderer: Sync gpu and cpu default alpha value 
Otherwise we might end up not passing the new value to the GPU.

3cc84d2860 transform: Make category public API 
Also rename it from GskMatrixCategory to GskTransformCategory.

58c2bea959 gl renderer: Stop determining the matrix category ourselves 
Use the category we get from transform nodes and add ops_ API to supply
one when we set a graphene_matrix_t directly.

1d3aa9207c gl renderer: Add a clip stack 
So we can check that the currently set clip is the first one and now
intersect with it. This first clip is always the entire viewport or the
entire render_area and we don't want to end up drawing things to a
texture because of it.

74dd05b45e gl renderer: add render ops for dumping the framebuffer 
So offscreen rendering can be properly debugged.

5907ff694f gl renderer: Render non-trivial transforms to a texture 
This way we can e.g. render rotated clips, borders, etc.

12378f0afa gl renderer: Expand matrix metadata extraction 
Instead of getting the translation x/y everytime we use the modelview,
get it once, when extracting the metadata. Do the same with the scale.
And save if the matrix is "simple" at all, i.e. if it only consists of a
translation and/or scale. This will be helpful later when we start
drawing transformed nodes on textures.

ef751bc809 gl renderer: Use stack to keep track of modelview matrix 
So we can avoid calculating metadata for matrices all the time.

d15df65a9d gl renderer: Save some matrix multiplications 
We do this for every single node, which is a little costly, especially
since the common case for the modelview matrix these days is a simple
translation. So, check whether the new modelview matrix is only a
translation matrix and if so, don't do a full matrix multiplication per
node.

d7af16c8e4 gl renderer: Render everyhing according to MV scale 
And not the surface's scale factor. This way the magnifier works.

We already drag a u_alpha uniform around in every shader, so use that
one.

832920c6ba gl renderer: Optimize text drawing 
Text nodes will almost always end up using the exact same texture and
the same program. So, in that case we can simply add vertex data for all
the characters we need to draw and use just one draw call.
