/**
* _cairo_error:
* @status: a status value indicating an error, (eg. not
* %CAIRO_STATUS_SUCCESS)
*
* Checks that status is an error status, but does nothing else.
*
* All assignments of an error status to any user-visible object
* within the cairo application should result in a call to
* _cairo_error().
*
* The purpose of this function is to allow the user to set a
* breakpoint in _cairo_error() to generate a stack trace for when the
* user causes cairo to detect an error.
*
* Return value: the error status.
