8fa5f638a5 [cairo-pdf-surface] Restore old_group for failed emit_meta_surface(). 
Ensure we restore the surface->current_group if we encounter an error
during _cairo_pdf_surface_emit_meta_surface() lest we leak the
current_group array.

8eb9fcf673 [win32] mask win32 printing vertex colors with 0xff00 per docs 
The range for the vertex color structures is 0x0000 .. 0xff00; I
think that this is an error in the docs, but strip out the low bits
just in case.

b8d7d62b08 Fix some trivial syntax warnings for -ansi. 
gcc -ansi -pedantic gives a few syntax warnings, principally for use of
'//' comments and a comma at the end of enumerators. Apply these
corrections as they are trivial.

4958789b9e [cairo-xlib-surface] Propagate error from _draw_image_surface() to surface. 
Instead of simply ignoring the error that may occur when we upload the

on the xlib surface.

32b78fffc3 [cairo-traps] Simplify the status interaction of traps_grow().

61ba63f3a0 [win32] remove ignore_operators flag from win32 printing surface 
Remove the ignore_operators fallback-avoiding workaround; if apps
want that same behaviour, they'll have to implement it themselves
by taking care when calling cairo_set_operator().

3da62fdd28 [cairo-xlib-display] Rescan the displays list during shutdown.

XCloseDisplay callback, we must rescan the list when we reacquire the
mutex in order to remove the display from the list.

2f22510e22 [cairo-xlib] Initialize the global mutexes. 
The xlib surface creation routines will eventually attempt to lock the
global _cairo_xlib_display_mutex. Under the default environment this is
a non-issue as the CAIRO_MUTEX_INITIALIZE/FINALIZE become no-ops under
pthreads. However, for the sake of correctness (i.e. to silence the
lockdep debugger!) insert a call to initialize the global mutexes at the
start of the public entry points.

81243ee7ef [cairo-scaled-font] Mask cannot be NULL so remove redundant check. 
We either generate a mask for the glyphs or throw an error and bypass
the check, so at that point mask can never be NULL and we do not need
the test.

f3d921baca [cairo-scaled-font] Destroy the zombie font. 
If we do not transfer the font to the holdovers array (because it has
been removed from the cache and left in a zombie state), destroy it.

dd0f2d851c [cairo-atomic] Hide compiler warnings for _cairo_status_set_error(). 
gcc treats cairo_status_t as an unsigned integer and so generates a
warning when passing it address as signed integer pointer to
_cairo_atomic_int_cmpxchg(). Use an ugly cast to hide the warning and
similarly to hide the warning about the unused result.

91d18eefe7 [cairo-type1-subset] Propagate error status (correctly!) 
Adrian Johnson pointed out a couple of mistakes in my previous attempt,
535e7c161b, to ensure propagation of errors
throughout the generation of the type1 subset.

This time the status member of the cairo_type1_font_subset_t is removed
in favour of simply return the error status from each function. This
completely avoids the issue of whether we overwrite a pre-existing error
status and confustion of status returns and the status member. The
removal of the status from the structure is possible due to its
short-lived nature - it is not exposed outside of the
_cairo_type1_subset_init() function, and is not shared by any other
piece of code.
