* babel_general_convert_from:
* @vtl: The TrackWaypoint Layer to save the data into
* If it is null it signifies that no data is to be processed,
* however the gpsbabel command is still ran as it can be for non-data related options eg:
* for use with the power off command - 'command_off'
* @cb: callback that is run upon new data from STDOUT (?)
* (TODO: STDERR would be nice since we usually redirect STDOUT)
* @user_data: passed along to cb
*
* Runs args[0] with the arguments and uses the GPX module
* to import the GPX data into layer vt. Assumes that upon
* running the command, the data will appear in the (usually
* temporary) file name_dst.
*
* Returns: %TRUE on success
