a8af7caae1 Rename gdk-private.h to gdkprivate.h
The extra - does not add any value.

0cc2d5559b Mark gsk_rounded_clip_node_new() return value as (transfer full)
Like all the other constructors for nodes already do. Without this,
newly created rounded clip nodes are leaked in bindings.

38eb182947 gsk: Collect opacity information
Collect information about whether to use offscreens
for opacity during node construction, so we don't
need to walk the tree repeatedly, later.

0eba21b2b5 gsk: Track disjointness of container nodes
This can be used to optimize some things in the

bf852bea24 Fix up preconditions of gsk_gl_shader_node_new
These were not quite right, and implied that args
may be NULL, when it really can't.

Fixes: #4739

20dcc31d19 rendernode: Limit diff region
Limit the diff region to 30 rectangles (randomly chosen because it
looked big enough to not trigger by accident and small enough to not
cause performance issues).

If the diff region gets more complicated, we abort to the parent node
and use its bounds as the diff region instead and then continue diffing
the rest of the node tree.

Fixes: #4560
Fixes: #2396

4e6ee28bcb gsk: Allow diffing code to abort
Now the vfuncs can decide they don't want to diff anymore, not just the
actual diff function.

2a08641f59 gsk: Add high depth rendernode api
Add private api to find out if the content
of a render node should be considered 'deep'.

The information is collected at creation time,
so there is no tree-walking involved when we
are using this information in the renderer.

Currently, this comes down to whether there are
any texture nodes with high depth textures in the subtree.
In the future, we may want to allow marking gradient
nodes in this way as well.

7e4b2b971f Revert "gsk: Stop enlarging text bounding boxes"
This reverts commit 87af45403a.

I've found that this change is needed to ensure that the
bounding boxes of text nodes encompass all the glyphd drawing.
Without it, we overdraw the widget boundaries and cut off
glyphs.

87af45403a gsk: Stop enlarging text bounding boxes

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.

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
bit anymore.

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
color glyphs, so we don't need to do that
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.

See https://gitlab.gnome.org/GNOME/gtk/-/issues/3841

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.

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.

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.
