gd2 default font path (Ticket #26897)

[mark brethen]

Ticket #26897 was an enhancement to link the gd2 default directory to an actual font directory in Mac OS X. It also mentions that the GDFONTPATH environment variable doesn't work if there's no shell involved, for example when wxMaxima directly calls gnuplot to get a png plot. I installed the wxMaxima port recently, however the message, "Could not find/open font when opening font "arial", using internal non-scalable font" is displayed, in spite of a patch that was added to the gd2 port.
