contained a few tests and the test suite was thus incomplete.

The bug mentioned in KNOWN_ISSUES was fixed in
2b3d8de11a, but the documentation was
not updated. Moreover, the header of KNOWN_ISSUES was 1.10-specific.

Beginning in 1.12, a crash can occur when the win32 surface's image size
does not cover the entire surface (e.g. due to clipping regions).
This patch enlarges the fallback surface created of the amount
necessary not to write past the end of the DIB. It assumes that
Clip applied to an HDC are clamped to (0,0,width,height) of the HDC.

The current code results in trace lines with the source surface being
pushed on the stack two times instead of one:
s1 s1 //ARGB32 48 48 similar-image % s2
Instead of:
s1 //ARGB32 48 48 similar-image % s2
This greatly confuses later commands when the script was replayed,
causing traces for trivial GTK3 programs to be unplayable, usually
yielding the following error:
"invalid value (typically too big) for the size of the input (surface, pattern, etc.)"
Drop the duplicated entry from the trace line printed by the
cairo_surface_create_similar_image() override.

With commit e691d242, the xcb backend started parsing the resources, just like
cairo-xlib does. One behavior from cairo-xlib was missing: If no Xft.rgba
property was specified, cairo-xlib defaults to the screen's subpixel order.
This commit brings that last bit of functionality to cairo-xcb (but currently
disabled due to commit e0c0a673).
This commits adds a new array to cairo_xcb_connection_t that contains the
subpixel order for each screen. There is also a new member in cairo_xcb_screen_t
which contains the subpixel order of that screen and which is initialized from
the array when the screen is constructed. With this in place, the
resource-parsing code can just pick the subpixel order from the screen if
needed.

The snapshot takes a reference to the target recording surface in order
to enable it for use by multiple treads. In order to balance this, the
other two sources of recording surface must also take a reference and
for us to release that reference after the replay.

On 32bit SPARC the scan converter was causing a SIGBUS due to an unaligned
memory access while accessing an int64_t. This memory accessing was to struct
quorem's rem member.
This crash occurred because the tor-scan-converter contains its own
implementation of a memory pool. This implementation only guarantees an
alignment of sizeof(void *), which is less than what a 64 bit type requires on
32bit platforms. This 4 byte alignment is guaranteed, because struct _pool_chunk
(which is the struct that is used for managing free space) contains elements of
that size and so the size of that struct is a multiple of this size as well.
This problem was introduced with commit 03c3d4b7c1.
To fix this problem, this commit introduces a int64_t member to struct
_pool_chunk that marks the beginning of the free data space. Thanks to this, the
compiler ensures proper alignment and sizeof(struct _pool_chunk) becomes a
multiple of 8.
However, previously the end of the struct marked the beginning of the data and
sizeof() was used for correctly calculating offsets to the data section. So,
just adding such a member would work, but would also waste some memory. To avoid
this, this commit also changes the rest of the pool implementation to
accommodate.

you were hoping for when c is initially 0.
Since there's nothing to swap in this case, just bomb out.

since the PS Document Structing Conventions impose a 255 character
line limit. PDF does not require wrapping.
pdf-operators is designed to emit the same output for PS and PDF.
Unfortunately some PDF interpreters don't like strings split with
'\\\n' and some PS interpreters don't like strings split with ')('.
So we are forced to make pdf-operators handling string wrapping
differently for PDF and PS.

These two images are mis-rendered (clearly evident from visual
inspection). By removing them, the test will fall back to the more
general format-specific images, huge-radial.argb32.ref.png and
huge-radial.rgb24.ref.png.
Note that the huge-radial.pdf tests still fail to pass, but the pdiff
looks more sensible.
