Well, that's nice, but couldn't the same thing have been made with a macro 
using nested gradient patterns? The syntax wouldn't be as neat, but it could 
still be made rather easy (if a bit clumsy):

#declare tile_map = array[13][2] {
{array[2]{0,0},array[2]{"png","1test.png"}},
{array[2]{0,2},array[2]{"png","1test.png"}},
{array[2]{0,4},array[2]{"png","1test.png"}},
{array[2]{1,1},array[2]{"png","2test.png"}},
...
}

Or a different approach:

#declare tile_map = array[13][2] {
{"0,0","1test.png"},
{"0,2","1test.png"},
{"0,4","1test.png"},
{"1,1","2test.png"},
...
}

And the macro could then be invoked with something like this:

pigment {MakeTileMap(6,6,tile_map)}
