The base image has 16 bits per channel, with colors that do not
have an exact corresponding 8 bit representation. The reference
image uses 8bpc, like the rgb24/argb32 formatted images which
the test outputs.
Before this change, images with RGB30, RGB96F, and RGBA128F formats
would have been given garbage xrender formats; now such images
use the fallback path and are converted to formats with an xrender
equivalent.
`_cairo_status_set_error` was using `_cairo_atomic_int_cmpxchg` to set
a `cairo_status_t` variable by casting a `cairo_status_t*` to
`cairo_atomic_int_t*`. `cairo_atomic_int` has a generic implementation
which is using a mutex. In the implementation, `cairo_atomic_int_t`
was typedef-ed to `cairo_atomic_intptr_t`. In a typical 64bit system,
cairo_atomic_intptr_t is 64bit and cairo_status_t is 32bit,
_cairo_status_set_error didn't work as expected.
Define `cairo_atomic_int_t` as an alias of `int`.
Added an assertion in `_cairo_status_set_error` to ensure
that `*err` has the same size with `cairo_atomic_int_t`.

GeometryRecorder class was calling _controlfp_s with MCW_PC to reset
the floating point precision to default. However, MCW_PC isn't
supported for ARM or x64 platforms. It reports an assertion failure
for them. And, Cairo isn't changing the MCW_PC setting. Removed the
calls. Also, removed `GetFixedX` and `GetFixedY` methods because they
called only `_cairo_fixed_from_double`.

Scaled font creation may fail if the font size is very large on
win32. But, don't leave the font face in an error state in such
case.
Fixescairo/cairo#607
There was an assertion in
`_cairo_recording_surface_acquire_source_image` to ensure the surface
isn't unbounded. However, this assertion was failing for
`record-paint` test on Windows.
Removed the assertion and return `CAIRO_INT_STATUS_UNSUPPORTED` if the
surface is unbounded.
Fixescairo/cairo#619
height (instead of integers).
Both cairo_pdf_surface_set_size and cairo_ps_surface_set_size passed on
their width and height arguments (of type double) directly to
_cairo_paginated_surface_set_size(cairo_paginated_surface_t*, int, int),
so the width and height were truncated.
A small part of the surface was then inaccessible for drawing (stripes
on the right and bottom of the surface).
This fixes that.

Lead to two memory leaks like the following:
98 bytes in 98 blocks are definitely lost in loss record 2 of 11
at 0x48407B4: malloc (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so)
by 0x4EB8789: strdup (strdup.c:42)
by 0x493C450: save_graphics_state (cairo-svg-glyph-render.c:2894)
This happened because the value of gs->dash_array was replaced without
freeing the previous value. This commit adds the missing free and fixes
the leak.

The original check-def.sh called make. In meson, check-def.sh is
replaced by two shell scripts, one for generating cairo.def, the other
for comparing with the library symbols.
The library filename appended to the cairo.def has been omitted as
this is only reqired in autotools builds where the cairo.def is also
to generate cairo.dll in the windows build.
make-cairo-def.sh is based on the cairo.def target in Makefile.am.
meson-check-def.sh is based on check-def.sh
