I have done something very similar to this using my eval_pigment() 
patch. Just call the eval_pigment() using the center location of each 
sphere and a pigment which uses an image_map, and use the returned color 
in a solid pigment for each sphere. The results would be the same as 
this. Plus, you can use any pigment, not just an image_map, and every 
file format POV supports is supported(not just TGA).
It also can use the interpolation built in to image_map...

And it isn't bloat, it is a useful feature which only took a small 
amount of code to implement.(although I think it currently only returns 
the rgb values, I haven't modified it to return f and t yet)
