eb23e23b03 ngl: Avoid cairo_to_png in debug output 
Just use a GL texture and gdk_texture_save_to_png,
it was made for this.

193b383739 ngl: Simplify and unbug texture download 
If we can't handle the texture, always just download_texture() it,
that way we are sure it's a memory texture.

9f2b847835 rendernode: Write the whole node 
It turns out g_output_stream_write_bytes() does not write the bytes.
It should be renamed to g_output_stream_write_some_of_the_bytes() maybe.

155a4fac5c Add vectorized half-float conversion 
We can't make the -4 versions inline, since
we use ifuncs for them, so make vectorized
versions.

65ce3eb207 Avoid hand-rolled color glyph information 
Followup to b244f31337. Pango provides color glyph
information for us now, so we don't need to steal a

6599cb001f gsk: Add font options to the glyph cache 
The cairo_t that we create to render glyphs for
the glyph cache needs to match the font options
that are supposedly governing how glyphs are
drawn.

Since we allow font options to be different per
widget in gtk, we need to have them at least at
the level of individual render nodes. Adding them
to the lookup key for the glyph cache has the
side effect of solving another problem: We are
not flushing the cache when font options change.

f1347f5841 gsk: Add font options to text nodes 
Since font options affect how the glyphs get rendered,
we need to pass the font options down from the gtk level
to where the glyph cache is populated.

Add a new gsk_text_node_new_full api that takes a
cairo_font_options_t in addition to the other parameters.

b244f31337 Use color glyph information from Pango 
Pango now sets a bit in PangoGlyphVisAttr for

ourselves anymore.

46a9538b6a Shrink shadow extents 
Long time ago, Cairo shadows in both GTK3 and 4 were drawn at a size about
twice their radius. Eventually this was fixed but the shadow extents are
still calculated for the previous size and appear unreasonably large: for
example, 141px for a 50px radius shadow. This can get very noticeable in
places such as invisible window frame which gets included into screenshots.

https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/3419 just divides the
radius by 2 when drawing a shadow with Cairo, do the same when calculating
extents.

915c229396 gsk: Use harfbuzz for color fonts

430b6f8fb1 gdk: Add GdkDisplay::init_gl vfunc 
The vfunc is called to initialize GL and it returns a "base" context
that GDK then uses as the context all others are shared with. So the GL
context share tree now looks like:

+ context from init_gl
  - context1
  - context2
  ...

So this is a flat tree now, the complexity is gone.

The only caveat is that backends now need to create a GL context when
initializing GL so some refactoring was needed.

Two new functions have been added:

* gdk_display_prepare_gl()
  This is public API and can be used to ensure that GL has been
  initialized or if not, retrieve an error to display (or debug-print).
* gdk_display_get_gl_context()
  This is a private function to retrieve the base context from
  init_gl(). It replaces gdk_surface_get_shared_data_context().
