Chris Rees 9179d6314c Update to 6.4.2: ... * elevation graphs for tracks using gnuplot; implemented by plug-ins contributed by Rudolf Martin (rudolf.martin_at_gmx.de). * for tracks, improved computation of total (or cumulative) ascent/descent, computation of rest periods, total resting time and average speed in motion, estimated time for a hiking trail; contributed by Rudolf Martin. * new configuration parameter: user temporary files directory; must be set correctly for GPSMan to work; it defaults to .tmp under the user GPSMan directory. * new user options: altitude threshold when computing cumulative ascent/descent, operating system commands to display an image file and open a terminal (command-line) window; default of altitude threshold is appropriate for GPS receivers with non-barometric altimeter. * change in default for user option (was a configuration parameter): the print command starts now by being empty (meaning unavailable). * new projections: Mercator spherical case, Equidistant Cylindrical, and their particular cases EPSG:3857 (also known as EPSG:900913, EPSG:102113) and EPSG:32663 (Plate Carree with WGS 84 datum); asked by Rudolf Martin. * in order to avoid ill formed or inconsistent data files, appending to a file is no longer an option when writing to an existing file except in the case of results of computations, real-time logs and contents of information windows. * windows presenting results that depend on the definition of a route or track, such as computations or graphs, may be closed when the item changes after being edited or being replaced when data is read-in; based on a change suggested by Rudolf Martin. * unavailable expression of plug-ins are now evaluated at top level so that global variables can be used. * explicit support for the Garmin GPS 72H receiver; with thanks to Justin Arundell and Julian Barragan who sent protocol lists.
