Hmm, downloading random .fig files from net I found that each of then is
matlab .mat named .fig. It has only one variable (structure) inside.
I suppose that name of this variable depends on matlab version used to save
a figure. I found only two types: hgS_050200 and hgS_070000.
Inside of such structure is a handle graphics (sub)tree.

I have only old octave 2.9.2, it reads hgS_050200 without compliants but
hgS_070000 gives many warnings:

   warning: range error for conversion to character value
