c5fe963159 Tests/invalid-matrix: Also mask FE_OVERFLOW (_EM_OVERFLOW) 
On Windows SDK <= 10.0.22621.0 (as we currently have in CI),
INFINITY is defined as a compound expression that overflows
at runtime.

From Windows SDK 10.0.26100.0 onwards, INFINITY is defined
as a literal expression (double) cast'ed to float. That
doesn't trigger the overflow at runtime. The previous behavior
can be retained by defining _UCRT_LEGACY_INFINITY.

3834a79741 Do not check for feclearexcept 
Unlike feenableexcept and fedisableexcept, which are GNU
extensions, feclearexcept is part of C99.

bc84f415bb Boilerplate/Win32: Switch to a DIB section 
The Win32 boilerplated works by positioning a test HWND
at (INT_MIN, INT_MIN) and drawing into the client HDC.
However, the image read-back always yields a blank image
(_cairo_boilerplate_get_image_surface).

The window is positioned offscreen, thus GDI returns an
HDC that is completely clipped, as GDI always clips to
the visible region of the client area. In short, every
drawing operation turns into a no-op.

It's probably best to use a bitmap target with a memory
DC. This commit reworks the Win32 boilerplate to target
a DIB section.

d04906aad6 Boilerplate: Adapt system / popen commands for Windows 
Both system() and popen() invoke the command interpreter;
that's CMD.exe on Windows (or whatever is specified in the
COMSPEC environment variable).

The Windows API supports forward slashes in paths just fine,
but CMD doesn't (well, it does in very specific cases [1]).
Forward slashes are always parsed as start of switches / options.

1ee2d140b6 Boilerplate: Open pipe in binary mode on Windows 
Avoids a translation from LF to CRLF, which messes up the
expected byte counts.

Note that popen() on GLibc does not support the 'b' mode,
so this change is for Windows only. From the POSIX.2024
spec:

 > The behavior of popen() is specified for values of mode of "r",
 > "w", "re", and "we". Other modes such as "rb" and "wb" might be
 > supported by specific implementations, but these would not be
 > portable features.

0ca7d6e6a2 Meson: Use mklink on Windows to create the srcdir link 
Create the directory symlink '<builddir>/test/srcdir' -> '<sourcedir>'
as done on UNIX. Invoke mklink /J to create a junction, which doesn't
require developer mode nor admin rights.

Note: we might also set the srcdir environment variable [1]

7a780896a1 win32: Fix MSVC build with dwrite disabled 
We now require at least Windows Vista.  When dwrite is disabled, declare
WINVER accordingly so we get the defines we no longer carry ourselves.
The default dwrite-enabled path already has a new-enough WINVER.

6ac5348308 The GDI coordinate system is inverted compared to cairo's here, so the 
delta-y value needs to be negated, otherwise glyph runs with non-zero 
y-advances will shift in the wrong direction.

See mozilla bug https://bugzilla.mozilla.org/show_bug.cgi?id=1962816 and
earlier https://bugzilla.mozilla.org/show_bug.cgi?id=454098 where this was
first discovered & fixed, but unfortunately was not upstreamed at that 
time.

1d3347a690 Fix a crash in the clipping code 
When cairo_is_all_clipped return true, we must not attempt
to change any of the clip fields, since it is pointing to
the static const __cairo_clip_all.

Moving the check for ->region into the 'if' is fine, since
it will always be NULL for _cairo_clip_all.

This was causing a crash in inkscape, see
