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.

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.

gl renderer: Use stack to keep track of modelview matrix

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.

Text nodes will almost always end up using the exact same texture and

the characters we need to draw and use just one draw call.
