I've thought of this, too. Should fit in the background statement, if
background could take a pigment statement, like this:
background{
pigment{
image_map{
..
}
}
}
The BNF would then have to be modified to something like this:
<background_statement> ::= background { <color_statement> |
<pigment_statement> }
<color_statement> ::= color <3dim_def> <3dim_vector> | <4dim_def>
<4dim_vector>
<pigment_statement> ::= pigment { <const_color_statement> |
<image_map_statement> }
<4dim_def> ::= rgbt | rgbf
<3dim_def> ::= rgb
etc.
