b4014daedf DWrite: Use twin font if default font not found 
If the default font is not found, return CAIRO_INT_STATUS_UNSUPPORTED
to cause _cairo_toy_font_face_create_impl_face to create the Twin user
font fallback.

5b18aeffbb Replace use of ctype functions with internal version where only ASCII chars are used 
In !309 Taylor R Campbell found a number of instances of ctype
incorrectly passed a signed char. In many cases, where only ASCII
characters are used, the code should have been using the cairo version
of the ctype function to avoid locale issues.

cairo_surface_set_subpixel_antialiasing() API and its use in quartz
and dwrite. Not sure if that is needed.

It compiles. Not tested.

81ecff3800 Remove BeOS support 
Nobody cares about BeOS in 2022, and it cannot be built with Meson anyway.

Removing the BeOS backend also allows us to drop the dependency on a C++
compiler and simplify the Autotools build considerably by removing all
the extra CXX targets.

2e0075e265 [quartz] Don't use CGContextDrawTiledImage for tiled patterns. 
CGContextDrawTiledImage turned up as a significant time-user while
profiling a benchmark created to evaluate
https://gitlab.gnome.org/GNOME/gtk/-/issues/3714. Without this commit
the benchmark is able to perform a mean frame rate of 2.19 frames per
second with a standard deviation of 0.09; with the commit the mean frame
rate is 2.37 fps, s.d. 0.30, both over 15 10-second samples. Student's
t-test reports a 9.8% likelyhood that the two represent the same
distribution.

64786613ee [quartz] Snapshot CGBitmapContext-mapped surfaces to cache CGImages. 
Motivation: Avoid need to recreate CGImages for unchanged surfaces,
an expensive operation, while ensuring that the CGImages are properly
freed and new ones created when the surface does change.

Thanks to Uli Schlacter for suggestion and coding guidance.

915dd79422 fixed some multiplications prone to overflowing their type 
In a couple of instances, code is present where two numbers are being
multiplied in a type like unsigned int, but immediately being casted
to a wider type like size_t.

This means, although the result can be any size_t value, the
multiplication can potentially overflow before it's used because
unsigned int has a smaller range of values.

In another more niche case, I also cast to size_t before multiplying
a signed integer, since the result is immediately used as an argument
to memcpy, which would give memory corruption if the value was negative
anyway.

c932bb7ae7 added missing documentation to cairo_font_options_status 
The documentation for cairo_font_options_status says it can return
either CAIRO_STATUS_SUCCESS or CAIRO_STATUS_NO_MEMORY, but the
implementation can also return CAIRO_STATUS_NULL_POINTER, which wasn't
mentioned.

8f7d039801 fixed some comparisons between signed and unsigned integers 
In some places, there were int variables being compared to unsigned
ints when they would never take a negative value, exposing some edge
cases that didn't need to be there.

a62eea4aec [user-font] Implement subpixel-positioning 
See:

https://github.com/harfbuzz/harfbuzz/pull/3411#issuecomment-1033118545
https://github.com/harfbuzz/harfbuzz/pull/3411#issuecomment-1033125311
https://github.com/harfbuzz/harfbuzz/pull/3411#issuecomment-1037765840

Basically the code in cairo-image-compositor.c:composite_glyphs()
is flooring glyph positions and putting some phase in the glyph-id.
This was being lost in the user-font backend. Fetch that and put it
in the recording-surface's device-transform translation, to be applied.
