_pixel_to_solid() used to assert that it got a known cairo_format_t.
However, this might not be the case when backends decide to use a pixman
format that is not representable by a cairo format (X and DirectFB are
examples for backends that do that).
This patch makes _pixel_to_solid() return NULL in that case and fixes
the callers to deal with it.

This new test (based on show-glyphs-many) checks that the glyphs
advances are respected along both axes.
9c0d761bfc introduced a bug which
regresses this test in quartz.
Thanks to Jeff Muizelaar for the report!
__cairo_path_fixed_is_rectangle() is used by the PS and PDF backends
to check if a path is equivalent to a rectangle when stroking. This is
different from being a rectangle when filling, because of the implicit
close_path appended to every subpath when filling.
Fixes stroke-open-box.

cairo-trace already depended upon HAVE_FUNLOCKFILE for its
thread-safety.
[This is a candidate for 1.10.]

It is not correct to rely on the version defined in render.h. The
Xrender.h header is independent and might not define some functions
available in RENDER 0.10.
Their availability must be detected at configure time and the stubs
must be defined only if the functions are not available.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=31906
cairo_tee_surface_create copies the device transform from 'master' to
the new surface. This is wrong since all the cairo_surface_wrapper
functions apply master's device transform themselves.

Even if the curve_to is completely within the current extents box, the
current point needs to be updated because the shape of following ops
depends on the position of the current point.
Fixes bug-extents.
The input of _fill_unaligned_boxes is (supposed to be) composed only
of disjoint rectangles, that can safely be passed to the rectilinear
span converter, but this function artificially introduces intersecting
rectangles when drawing non-aligned boxes.
Using non-intersecting rectangles is easy and makes the code correct.
Fixes rectilinear-grid.

The rectilinear scan converter assumes disjoint rects as input, but
cairo-image passes intersecting rectangles to it.
This test shows that image and any backends passing through it for the
rasterization (fallbacks, vector backends whose renderer is
cairo-based) fail in compute the corners of intersecting rectangles
correctly.

_cairo_memory_stream_destroy was changed to take an unsigned long
instead of unsigned int, and the two callsites in cairo-gl-shaders.c
weren't updated.
Sun Studio Compiler complains:
"cairo-xcb-surface.c", line 585: void function cannot return value
even if the returned value is void.
Some minor code restructuring removes the issue.
Painting of some pattern was broken because the paint operation was
implemented as a fill to a rect containing the clip, but this rect was
not transformed as appropriate (using the cairo_to_ps matrix).
PDF simply fills the whole surface rect, so we implement the same
behavior in PS.
Fixes clip-group-shapes-circles, clip-stroke, linear-gradient-extend,
linear-gradient-one-stop, radial-gradient-one-stop.
The use of ActualText in a marked content sequence is a PDF 1.5
feature.
A 'use_actual_text' flag linked to the PDF version has already been
implemented in pdf-operators but for some reason this flag had not
been used to control the use of ActualText.

In 06e9caf861 the type of the variables
was changed, but the type used to compute the allocation size was not.
Fixes a crash in user-font-mask (test-fallback backend).
