a8d4fed67a cairo-perf-diff-files: Remove some overzealous option parsing. 
The code was complicated and confusing, and only existed to implement
undocumented and unneeded command-line options.

29670d3766 Add a content value to solid patterns 
This allows for the surface acquired from the pattern to have the
same content. In particular, in a case such as cairo_paint_with_alpha
we can now acquire an A8 mask surface instead of an ARGB32 mask
surface which can be rendered much more efficiently. This results
in a 4x speedup when using the OVER operator with the recently
added paint-with-alpha test:

Speedups
========
image-rgb  paint-with-alpha_image_rgb_over-256 2.25 -> 0.60: 4.45x speedup
███▌

It does slowdown the same test when using the SOURCE operator, but
I don't think we care. Performing SOURCE with a mask is already a very
slow operation, (hitting compositeGeneral), so the slowdown here is
likely from having to convert from A8 back to ARGB32 before the
generalized compositing. So if someone cares about this slowdown,
(though SOURCE with cairo_paint_with_alpha doesn't seem extremely
useful), they will probably be motivated enough to contribute a
customized compositing function to replace compositeGeneral in which
case this slowdown should go away:

image-rgba paint-with-alpha_image_rgb_source-256 3.84 -> 8.86%: 1.94x slowdown

fea5336e2d Allow fbCompositeSrc_x888x8x8888mmx when destination has alpha 
Previously the check for this optimized function would only allow
the function to be called if the source and destination had
identical formats. But the function doesn't read the destination
alpha (if any) so can be used when it exists as well.

(Thanks to Jeff Muizelaar for pointing out this problem.)

72b812be8c perf: Add new paint-with-alpha test 
MacSlow noticed that cairo_paint_with_alpha is much slower than
it should be, (and jrmuizel has a nice plan for fixing the
performance bug).

302f1146da Fix two bugs in documentation code sample of cairo_arc 
The sample code for drawing an ellipse had width and height
reversed in the call to cairo_scale, and also had both
incorrectly inverted.

260dcb316e Add a _cairo_error() to png_simple_error_callback() 
With the introduction of the error callbacks for PNG, we have the
opportunity for the user to set a breakpoint (via _cairo_error) at the
point the error is first rasied.

0fce7e85a1 Do not print out libpng error messages to stderr. 
We wish to avoid writing to file descriptors (and streams) that are
outside cairo's control. In this case, the messages are superfluous as
the errors are propagated via the cairo_status_t returns.

3b46e105bd [util] Import my malloc wrapper that prints simple statistics 
To build, do:

	make malloc-stats.so

inside util/, and to use, run:

	LD_PRELOAD=malloc-stats.so some-program

For binaries managed by libtool, eg, cairo-perf, do:

	../libtool --mode=execute /bin/true ./cairo-perf
	LD_PRELOAD="../util/malloc-stats.so" .libs/lt-cairo-perf

The code also includes Jeff Muizelaar's libbacktracesymbols that
is a much better implementation of backtrace_symbols() than what
is provided by glibc.  That can be built by:

	make backtrace-symbols.so
