Whenever you group several objects in an union, if you apply any texture 
to the union itself, then that texture will be applyed to every objects 
of the union. The exeption is any object that already have their own 
texture that will retain that individualy applyed texture.

So, you can have this:
union{
  object{GlassPane}
  object{MyBox}
  pigment{gradient x+y color_map{[0 rgb 1][1 rgbt 1]}scale 3}
}
