usage: cairo-trace [--no-file|--silent] command
cairo-trace will generate a log of all calls made by command to
cairo. This log will be stored in a file in the local directory
called command.pid.trace.
Whatever else happens is driven by its argument:
  --silent  - disables the overriding of stdout by cairo-trace.
              The trace file is still generated, but your application
	      is free to continue to use stdout.
  --no-file - disables the generation of an output file

Enviroment variables understood by cairo-trace:
  CAIRO_TRACE_FLUSH - flush the output after every function call.
