The problem you're seeing is quite a bit larger than "paperposition".   
In my octaverc I set several property defaults. See below ...

if compare_versions (version, "3.1.0", ">=")
  set (0, "defaultaxesfontname", "Helvetica")
  set (0, "defaultaxesfontsize", 14)
  set (0, "defaultaxesinterpreter", "tex")
  set (0, "defaultaxesxtick", [0:0.2:1])
  set (0, "defaultaxesytick", [0:0.2:1])
  set (0, "defaultaxesztick", [0:0.2:1])
  set (0, "defaultaxesxtickmode", "auto")
  set (0, "defaultaxesytickmode", "auto")
  set (0, "defaultaxesztickmode", "auto")
  set (0, "defaultaxesactivepositionproperty", "outerposition")
  set (0, "defaultfigurepapertype", "usletter")
  set (0, "defaultfigurepapersize", [8.5 11])
  set (0, "defaultfigureposition", [440 314 560 420])
  set (0, "defaultfigurepaperposition", [0.25, 2.5, 8, 6])
  set (0, "screensize", [1, 1, 1440, 900])
  set (0, "screenpixelsperinch", 1440/14)
  edit editinplace true
  edit home .
endif

I'm not sure where such defaults should be set in the sources.  
However, I am rather confident it is at a low level. If someone can  
offer some guidance, preferably give an example of code setting just  
one of these (for the c++ deficient like myself) I'd be happy to add  
these as well as others.
