Bryce Harrington 18d66c88a2 cairo-script: Error if asked to decompress with missing compression lib 
This quells the following warning:

warning: enumeration value ‘LZO’ not handled in switch [-Wswitch-enum]

The LZO enum value is defined and used elsewhere, even if lzo support
isn't available.

This situation might arise if cairo scripts were generated on one system
with lzo, and then replayed on a system without it.  For now simply
error out if this occurs.

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.
