Even if we disable font fallback, after adding Cantarell Regular
to the custom fontmap, fontconfig will helpfully synthesize
Cantarell Bold for us. So, just don't check for the font at all.
If there is a url, add it to the fontmap and leave it up to the
serializing code to ensure that we don't end up with duplicate
fonts.
The hb face is is a wrapper around the font file, which is what
we need to track here, since we want to subset and serialize each
used font file exactly once.
When serializing nodes, collect the glyphs that are used from
each font, subset the font to that set of glyphs, and embed it
into the node file. We are careful to preserve the glyph IDs,
so our text nodes transparently work with the subsettted fonts.
This way, we can simply duplicate the keys as separate pointers to store
the corresponding Vulkan handles so that we can safely hash them, as
Vulkan handles may or may not be pointers depending on the target
platform.
This will fix builds on 32-bit Windows at least.
This function does not use the standard __cdecl calling convention on
Windows, meaning using g_clear_pointer() on it directly will cause
crashes on 32-bit Windows. Just call it directly if the GLsync it uses
exists.
Switch symbolc icon drawing from color-matrix to mask nodes
make the performance of the iconscroll demo crater (from 60fps
to 10fps).
Apply the same optimization we already have for color-matrix
nodes when drawing mask nodes. This gets us back to 60fps.

On Windows, gsize is a long long unsigned. The compiler complains about
that.
Use G_GSIZE_FORMAT which translates to %llu on Windows, %lu on most
platforms, and sometimes just %u on rare cases.
Due to rounding errors, it is possible after intersecting a lot of
rectangles to end up with a tiny size for an offscreen. And because we
allow an epsilon before ceil()ing to an integer (see commit afc7b46264
for details) it is now possible that we end up with a size of 0.
Avoid that by always enforcing a minimum size of 1px.
Test included
The test uses a different codepath to arrive at the same problem - it
specifies the small size instead of triggering it via rounding errors
and clipping like the original bug (and most likely the more common case
to encounter this problem.

Use a format of
[XXX] SYMBOL DETAILS
where SYMBOL indicates the offloading status:
🗙 - no offload
▲ - offload above, with background
△ - offload above, no background
▼ - offload below, with background
▽ - offload below, no background
The VK_IMAGE_LAYOUT_UNDEFINED layout means that the data hold by the
texture can be discarded, and we don't want to discard it. Because the
Vulkan spec is unclear (see [1] for a discussion), err on the side of
caution and use VK_IMAGE_LAYOUT_GENERAL.
Fixes import failures with WebKit.

Spew a bit less per-frame. Unfortunately, we still spew for
every frame, and fixing that would require more extensive
refactoring to centralize all logging in gskoffload.c
The intent of this change to get wider testing and verify that the
Vulkan drivers we get to use in the wild are good enough for our
needs. If significant problems show up, we will revert this change
for 4.16.
The new preference order is vulkan > ngl > gl > cairo.
The gl renderer is still there because we need it to support gles2.
If you need to override the default renderer choice, you can
still use the GSK_RENDERER environment variable.
