915c229396 gsk: Use harfbuzz for color fonts 
harfbuzz has all the information we need, so we
can avoid poking directly at freetype apis. Also
drop the caching of color glyph information until
it turns out to be a problem.

a7a2dbc3ea gsk: Cache per-glyph color information 
We don't really want to load the bitmaps every time
we create a render node, so do it once and cache the
information on the PangoFont.

bb9dccd773 gsk: Mark color glyphs

b695ef9168 gsk: Add a shortcut for a common transform case 
Add a private getter for the translation part of a
transform node, to avoid pulling it out of the transform
over and over.

2c33550048 gsk: Avoid empty glyphs early 
Strip out PANGO_GLYPH_EMPTY when text nodes are
constructed. Then we don't have to check this special
case in the inner loop in visit_text_node.

2d5dd7b3d7 gsk: Make rendernode diffing smarter 
Allow comparing container nodes to any other
node, by pretending the other node is a single
child container (if it isn't one already).

This fixes a glitch where we redraw the full
entry text when the blinking cursor goes to
opacity 0, since GskSnapshot then optimizes
away first the opacity node, and then the
single-child container.

of GLib.

161ddcfa92 gsk: make render node getters const 
This also removes the return if fail macros from these as a good portion
of them didn't have them anyway. I think it's fair to say that access to
these incorrectly is a programmer error.

It significantly reduces the amount of code generated into generally a
movss,ret.

0d2ea14ac1 types: fix various use of volatile in type registration 
The use of volatile was incorrect in GLib and has been that way for
a long time. Recently however that has changed, and this makes GTK
follow suit to avoid using volatile in the type registration.

See also: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719

Combined with the above merge request for GLib, this fixes a large
number of compilation warnings when using Clang.

7ea755e206 Add GskGLShaderNode and GskGLShader 
A GskGLShader is an abstraction of a GLSL fragment shader that
can produce pixel values given inputs:
 * N (currently max 4) textures
 * Current arguments for the shader uniform
Uniform types are: float,(u)int,bool,vec234)
There is also a builder for the uniform arguments which are
passed around as immutable GBytes in the built form.

A GskGLShaderNode is a render node that renders a GskGLShader inside a
specified rectangular bounds. It renders its child nodes as textures
and passes those as texture arguments to the shader. You also pass it
a uniform arguments object.

2fa9dddea6 gsk: Remember border node uniformity 
Lots of border nodes have all the same width and the same color.
Renderers might be able to simplifty that, so keep an extra bit per
border node.
