Add a --colorflip option to the compare-render test. This applies
a color matrix to the node, which has the intended side-effect of
convincing the Vulkan renderer to use its uber shader, so we get
test results comparing the uber output to its non-uber siblings.
We were turning off hinting and subpixel positioning if the
transform isn't 2D affine. The idea behind this was that transforms
likely indicate animations, and for animations, this may reduce
jitter. But the heuristic of transform==animation is not very
reliable, and we pay for this with a jump from hinted to unhinted
at the beginning and end of it. Also, the heuristic does not even
work for the most relevant 'animation' we have today: scrolling.
So, lets drop this for now. We can revisit it later.
When getting the hinted version of fonts, they often come in sequentially.
This helps reduce overhead in many sequential gtk_text_node_new() on with
fractional scaling as you see from GtkSourceView.
Some maps are used for read only and do not require uploading contents
back to the GPU afterwards. In other cases, we can often upload less than
the fully allocated buffer size.
The documented icon flags didn't match the actual constants used by GTK when
reading and updating icon theme cache files. Fix the values of flags in the
documentation.

When transforming an empty clip, it stays empty.
Previously, we were setting it to CONTAINED, but that's wrong, because
the bounds are not contained in the clip, the clip is contained in the bounds.
This reverts part of commit a51c6aed47.

Test included.
The test is disabled for Cairo because the Cairo blurring code can't
deal with scaling, which makes things come out wrong for the test that
checks that we do the right thing with the blur radius when scaling.

The emoji presentation selector (FE0F) was being appended to every emoji
sequence inserted by GtkEmojiChooser and GtkEmojiCompletion, often
leading to invalid sequences. Modify the emoji data to include FE0F
only when necessary, and change skin tone handling to account for cases
where the generic (no tone) variation needs a presentation selector.
When scaling a font or changing font options, we need to be
careful to preserve the dpi as well, otherwise the rendering
might leak out of the node bounds, leading to spectacular
glitches.
Fixes: #6508
Simplify the AT-SPI implementation by having a convenience function to
extract the text attributes of a GtkAccessibleText, with or without the
default attributes.
This is done with a NSCursor whose content is an NSImage. Image pixels are filled by a NSBitmap, and the format is premultiplied RGBA. So we can just use the texture downloader with GDK_MEMORY_R8G8B8A8_PREMULTIPLIED format.
