34976a791c gskpango: Make get_color a bit shorter
Don't copy from crenderer->fg_color just to override from the local
color again.

7c73f2fb02 GskPango: Allow specifying a custom shape snapshot handler
We will need this for GtkTextView to render the textures in it.

10e4c04e61 Use style values directly
Replace uses of gtk_css_style_get_value with direct access,
throughout the tree. We don't replace all uses, just those
where we are dealing with a fixed property. Be careful to
handle the currentColor special case for color properties.

Just go to the css nodes directly.

30f55c4d07 Remove a redundant vfunc
PangoRenderer has a perfectly adequate default
implementation of draw_glyphs, no need to duplicate that.

3278e9ab6c Render error underlines as render nodes
Use a sequence of transformed squares,
instead of a cairo node. The drawing is not
identical to the previous code, but reasonably
close.

4ff9163c47 textview: port GtkTextView to GskPangoRenderer
This removes the use of GtkTextDisplay (a PangoRenderer) to use
the GskPangoRender which generates render nodes. Part of this means
improving the GskPangoRenderer to support the necessary features for
displaying a GtkTextView.

Primarily, this is a merging of GtkTextDisplay features into
GskPangoRender. Additionally, GtkTextDisplay was removed to allow for
gtk_text_layout_snapshot() to be implemented elsewhere.

0d119f81c8 snapshot: Refactor text rendering
The code didn't change, it was just shuffled around to make the
with_bounds() versions of the text rendering unnecessary and instead
pass through the generic append_node() path.

73b4a62f51 snapshot: Redo debug messages
Instead of every snapshot function having debug messages, have an
explicit gtk_snapshot_push_debug() function that appends a debug node.

4f3c7cd48a gsk: Make gsk_text_node_new_with_bounds private
We pulled out the bounds calculation for performance reasons, but the
caller can't know how to properly compute them. Inside gtk+, we can do
that but it's not good enough for public API.

2db43edbd6 snapshot: Don't handle clip anymore
If widgets want to clip things, they now need to do it themselves.

By not taking care of clip, we avoid the need to track clip. And by not
tracking clip, we can avoid all unnecessary cache invalidations that we
were doing for render nodes whenever the clip changed.

And when you are scrolling, the clip changes *a lot*.

9b83116fcb snapshot: Export gtk_snapshot_append_layout()
This is the equivalent snapshot function to pango_cairo_show_layout().

Not to be confused with gtk_snapshot_render_layout(), which is the
equivalent to gtk_render_layout().

e6d24f4c15 snapshot: Make gtk_snapshot_append_node() take care of offset

8a062f4f9a gskpango: Don't create text nodes for clipped text
Measure the text here directly and check if the created node bounds will
be clipped away before even creating the text node.

a687fd9aeb gtk/gskpango.c: Use g_snprintf()
This fixes the build of GTK+ master on Visual Studio 2013 (and possibly
others) as snprintf() may not be supported even if the required C99
features are supported by the compiler.

b0e8d8483d More work on text nodes
This commit takes several steps towards rendering text
like we want to.

The creation of the cairo surface and texture is moved
to the backend (in GskVulkanRenderer). We add a mask
shader that is used in the next text pipeline to use
the texture as a mask, like cairo_mask_surface does.
There is a separate color text pipeline that uses the
already existing blend shaders to use the texture as
a source, like cairo_paint does.

The text node api is simplified to have just a single
offset, which determines the left end of the text baseline,
like all our other text drawing APIs.

1b7f08171a gskpango.c: Include cairo.h consistently
The other source files use "#include <cairo.h>", so we should do
likewise.

7bb202e4a2 Add a workaround for vulkan crashes
I see 'out of memory' errors and crashes inside libvulkan when
creating nodes that have empty bounds and end up in the fallback
paths, like a shadow around an empty text node. Prevent this
by not creating text nodes in that case.

a367d34949 Use a text render node in GskPangoRenderer

82e8f3a542 Add a Pango renderer
Copy the PangoCairoRenderer into GTK+, rename it to GskPangoRenderer,
and strip it down far enough to build without private pango apis.
This means we currently don't support hexboxes or shapes.

Currently, this lives in gtk, but it might be nicer to put it
in gsk eventually.
