Comment (by hamish):

 ok, second cut committed with r41215.

 I'm still not sure about the terms for png_set_background():

  source:grass/trunk/raster/r.out.png/main.c at 41215#L241


  - how to setup png_color_16p;
  - if r,g,b given for png_color_16p, set need_expand = 0 ?
  - set background_gamma = 1.0?
