Try using functions in POV-Ray.  You would also be able to use procedural
textures instead of an image map then.

I don't really understand why the uv-coordinates are so curved though. 
Wouldn't it be easier for the program to use much simpler coordinates
following the contour of the shape?

When you have the function for the pigment:

#declare fn_Color=
  function {
    pigment {
      ...
    }
  }

And mapping functions for the coordinates;

#declare fn_X=
  function {
    [x coordinate depending on x and y (and possibly z)]
  }

#declare fn_Y=
  function {
    [y coordinate depending on x and y (and possibly z)]
  }

You use a pigment:

#declare PigX=
  pigment {
    function { fn_Color(fn_X(x, y, z), fn_Y(x, y, z), z).red }
    color_map {
      [0 color rgb 0 ]
      [1 color rgb 3*x ]
    }
  }

#declare PigY=
  pigment {
    function { fn_Color(fn_X(x, y, z), fn_Y(x, y, z), z).green }
    color_map {
      [0 color rgb 0 ]
      [1 color rgb 3*y ]
    }
  }

#declare PigZ=
  pigment {
    function { fn_Color(fn_X(x, y, z), fn_Y(x, y, z), z).blue }
    color_map {
      [0 color rgb 0 ]
      [1 color rgb 3*z ]
    }
  }

#declare Pig_Final=
  pigment {
    average
    pigment_map {
      [1 PigX]
      [1 PigY]
      [1 PigZ]
    }
  }
