Emanuele Aina cca8b1960b cairo-trace: Fix duplicated surface push on similar-image
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.

Cairo Utilities
===============

There are a varieties of utilities we use with cairo.


backtrace-symbols
-----------------

This is a small shared library designed to be preloaded by the
linker and its purpose is to make the backtrace_symbols() function
of glibc produce more useful source reference information.

Build by:

	make backtrace-symbols.so

and use by:

	LD_PRELOAD=$PWD/backtrace-symbols.so app-to-run

This code should be contributed back to glibc at some point.


malloc-stats
------------

This is a small shared library designed to be preloaded by the
linker and its purpose is to make the malloc_stats() function
of glibc produce more useful information.

Build by:

	make malloc-stats.so

and use by:

	LD_PRELOAD=$PWD/malloc-stats.so app-to-run

This works best when backtrace-symbols is in use.  That is:

	LD_PRELOAD="$PWD/backtrace-symbols.so $PWD/malloc-stats.so" app-to-run


cairo-trace
-----------

This tool can be used to trace all the cairo function calls made by an
applications.  This is useful for either extracting a test case triggering
a bug from an application, or simply to get a general idea of how an
application is using cairo.


cairo-api-update and xr2cairo
-----------------------------

These two scripts were used to convert source code written for pre-1.0
cairo to newer API.  See $(top_srcdir)/PORTING_GUIDE for more information.

These files are obsolete now and may be removed in a future version.


cairo-view and waterfall
------------------------

These are two pycairo scripts useful for testing the toy font backend.
