4c7a8afb3b Remove the approximate glyph bounds check 
We are trying to get an approximate bounding box for
the extents of a glyph string and use it for bailing
early if there's nothing to do, but the code computing
that approximation makes invalid assumptions: It assumes
that a glyph never extends further than max-advance-width
before or after its position. That is not true in general,
as can be seen in https://gitlab.gnome.org/GNOME/gtk/-/issues/4132
In the example there, we have a monospace fonts with ligatures
that have a negative lsb of two or three times the glyph width.

The optimization here could theoretically be fixed by iterating
over the font once to determine suitable values for how far
glyphs can extend before or after their position, but this
patch just removes it.

068e9b2eb4 Fix malloc overflow check warning 
To fix this warning:

../src/cairo-malloc-private.h:83:32: warning: comparison is always false due to limited range of data type [-Wtype-limits]
   83 |   ((size) != 0 && (size_t) (a) >= SIZE_MAX / (size_t) (size) ? NULL : \
      |                                ^~

Create two new macros to do the overflow checks:
_cairo_addl_size_t_overflow and _cairo_mul_size_t_overflow. Implement
them using compiler builtins where available.

Update cairo-malloc-private to use these fuctions and add an overflow
test to test the functions.

6c3b7a487b meson: Build the API reference 
The Meson build system should build the API reference using gtk-doc,
like the Autotools build does.

The option is called `gtk_doc`, which matches the existing practices in
various projects using Meson and gtk-doc.

4e859ddb19 Fix compositing non-color glyphs in one case 
The intention here is: "if show_text_glyphs is unsupported,
try show_gyphs". We need to make sure to set the status to
unsupported before checking it, otherwise we end up looking
at the status that was set by composite_color_glyphs if
show_text_glyphs is NULL.

This showed up in https://github.com/harfbuzz/harfbuzz/issues/2675

3ee18ffc28 Added extra check for HAVE_STRNDUP in Win32 Mingw Meson build 
Mingw on Windows defines the strndup function, but it's not actually usable because string.h doesn't exist. See details on the Meson bug here: https://github.com/mesonbuild/meson/issues/3672

Note that although Meson marked this bug as "fixed", it's only fixed in the case where you're using `prefix : '#include <string.h>'`.
