Clearly demonstrated by using the test-base with the recording surfaces
and exemplified by the fallback-resolution with PDF, which is *almost*
fixed!
We're very close to making a release candidate for 1.12 now...

The clipping code was modified to handle partial boxes itself, so update
the base compositor to simply use the core clipping code and avoid
double application.
Even for a vertical edge, we still need to bias the error term otherwise
later we will find the error term is too larger and advance a pixel on
every row.

If the mask does not intersect the clip, then there is no drawing to be

When estimating the maximum number of spans required for a particular

Currently you can only specify that a cairo_ft_font_face_t should
synthesize a font (to make a bold variant) through an FcPattern. That is
direct consumers of the public cairo-ft API have no control over the
synthesize options.
Rectify this by creating some public API to allow control over the
synthesis flags, and include the ability to construct an oblique as
well an embolden font.
Based on a patch by Deokjin Kim <deokjin81.kim@samsung.com>.

Not 100% improvement, there are still a variety of failures with

Complete the task started in cd4b2d843b by
remembering to compute the insertion hash on the original font face as
well as the lookup hashes. Also take advantage by deferring resolution
of the implementation for the font face until after we fail to find an
already constructed scaled font.

Ordinary patterns have their device offsets pre-baked into the pattern
matrix. The difference with raster patterns is that the surface is
generated upon use by the pdf,ps and so its device offset is not known
until then.

I need to remember that the translation for the pattern matrix is the
inverse of the translation for drawing.

Rather than store a command to copy from a reference of another recording
surface onto this, just replay the other recording surface.

Borrow the technique for installing a proxy-snapshot developed for
acquiring the image from a recording surface.
This prevents the cairo from exploding and using up all memory due to
infinite recursion, but it does break a few tests that perform
self-copies with differing transformations.

I forgot that creating any image by defaults results in pixman
calloc'ing the pixel data and so cairo helpfully sets the is-clear flag
on the surface.

Rather than compress the copies into a clip + copy, iterate over and
perform each copy separately so as to avoid the confusion for
window-to-window copies and the solitary GC->pCompositeClip.

In the midst of trying to simply export the
_cairo_image_surface_get_font_options() for subclassing, I accidentally
decoupled it from the image surface backend. Mea culpa.
Fixes regression from 8bea52bb (Add preliminary damage tracking), which
should not have even touched the backend structure except for an ugly
rebasing.

and make it more obvious that we're not doing OOB accesses.
They were not possible because of the parity constraint, but by
guarding the highest index with which we access the data in the loop,
the correctness information is completely contained in the loop code.
Fixes:
cairo-stroke-style.c:199:2: warning: cannot optimize loop, the loop
counter may overflow [-Wunsafe-loop-optimizations]
_cairo_path_fixed_last_op() contains an assertion, which gcc doesn't
like to inline. Since it is a static function, which basically
accesses a value, gcc will inline it anyway when assertions are
disabled, so remove the "inline" hint to reduce gcc warning noise when
doing debug builds.
Fixes:
cairo-path-fixed.c: In function '_cairo_path_fixed_drop_line_to':
cairo-path-fixed.c:373:1: warning: inlining failed in call to
'_cairo_path_fixed_last_op.isra.5.part.6': call is unlikely and code

As we return the child image to the user and so perform the reference
tracking on it and not the parent win32 display surface, we need to add
a call to destroy the parent from the image surface. This of course
complicates the normal scenario of destroying the parent first, and so
in that case we need to unhook the image->parent before freeing the
surface->image.

I suspect I may split the win32 code into a few more files, so move it
