usage: cairo-trace [--no-file] 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:
--flush - Flush the output trace after every call.
--no-file - Disable the creation of an output file. Outputs to the
terminal instead.
--no-callers - Do not lookup the caller address/symbol/line whilst tracing.
--no-mark-dirty - Do not record image data for cairo_mark_dirty()
--compress - Compress the output with LZMA
--profile - Combine --no-callers and --no-mark-dirty and --compress
Enviroment variables understood by cairo-trace:
CAIRO_TRACE_FLUSH - flush the output after every function call.
CAIRO_TRACE_LINE_INFO - emit line information for most function calls.
