Details:

When running label2rgb() on a labelled image with labels larger than 65535
(the 16 bit unsigned integer limit), the function returns an error:

>> label2rgb(lw);
error: ind2rgb: X must be an indexed image
error: called from
    ind2x at line 32 column 5
    ind2rgb at line 49 column 10
    label2rgb at line 126 column 8


Example code:

lw = zeros(10, 10);
lw(1, 1) = 65535 + 1;
label2rgb(lw);
