In the final analysis, what matters is not that the first-chosen technique is the one that is used for figure production, but that the figure is successfully produced in reasonable time. There have been many cases where hours or even days have been spent trying to pummel one PostScript file into shape, where time might have been more efficiently spent in using another graphic generation package to copy the chosen picture by hand. The methods described above are all known to work reasonably well, but bugs can appear in the strangest of places, and it is best to be flexible so as not to waste time. One of the methods is bound to work successfully......we hope!
