I expect I wrote the original support for tikzstandalone. The approach was to 
produce both a tex-file and a tikz-file. The tikz-file came from gnuplot. Gl2ps 
was able to generate a pgf-file, but that never worked for me. Since then there 
has been changes to the standalone output and the gnuplot backend. During those 
changes, the tikzstandalone must have been broken/disabled.

There is a function print.m:latex_standalone() whos handle is passed into 
__opengl_print__.m and __gnuplot_print__.m as part of the “opts” structure. The 
approach that was intended to be used for tkzstandalone with gnuplot is 
essentially equivelent to what is implemented for opengl (I haven’t tested 
tikzstandalone with opengl, but I expect it works).
