I'm not quite sure I understand what you mean by 1)+2). Since the
legends are being displayed so well with my legend code and the gnuplot
backend, as long as the activepositionproperty of the axis is
"position", I'm now thinking its better to remove the gnuplot legend
code entirely and use the same frontend legend code for all of the
backends. This just means the FreeType and fontconfig are required for
the gnuplot backend as well as they are used to estimate the text
extents in gnuplot... The current text extents code in Octave estimates
pretty well the text extents in gnuplot, at least with the wxt and x11
terminals I've tested with.
