e347a7a7c3 PS: Add support for images with bilevel alpha 
This patch eliminates two sources of fallback images. The alpha value
of each pixel in argb32 images are checked. If all alpha values are
255 the image is treated the same as rgb24 images. If all alpha values
are either 0 or 255 and the PS level is 3, a Type 3 image (image +
mask) is emitted.

af5cdde34d PS/Win32-printing: remove redundant checks from _analyze_operation 
The check for supported operators is performed earlier in this
functions so these two checks in not required.

b5fa273c9a Add PS reference images for tests using create_similar 
before the PS meta surface pattern patch these tests
had image fallacks in the PS output and did not require
a PS reference image.

e5b01e6797 [Makefile.am] Add missing headers and reference images. 
Andrew Jorgensen spotted that make dist was missing a few headers needed
for compilation and running make distcheck had spurious failures. Add
the missing files to the distribution and a silly one-liner to check for
missing reference images.

b7adcf67f8 [cairo-path-stroke] Jump to cleanup after error. 
Incorrect early return in _cairo_stroker_curve_to() after
_cairo_stroker_join() resulted in leaking the local spline and pen.

0222c02d95 [cairo-pdf-surface] Return UNSUPPORTED from _to_unicode_stream(). 
Distinguish the UNSUPPORTED case where the font backend does not
support conversion to unicode from other fatal errors by returning a
status value rather than using stream.id == 0 to indicate any error.

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.

Replace xargs and rm with the binaries found by configure and drop the
passing of NUL-terminated strings as that is a GNU extension.

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(). 
Simply return the error status from the traps_grow() function rather
than having an assignment in the return function and then immediately
another assignment of the error to the status member at its callsite.

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().

b12ed375cf [ChangeLog.mk] Fix changelog generation rules 
Previously it was trying to get logs of 1.2.0..1.4 while I really meant
was 1.2.0..1.4.0.  It was a simple typo.

3da62fdd28 [cairo-xlib-display] Rescan the displays list during shutdown. 
As we drop the list mutex whilst calling the hooks during the
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.
