Accept indexed images with color values below the first colormap entry (bug #41851).
Change made for Matlab compatibility.
* ind2gray.m: Change %!tests to accept an indexed image with colors below the
first entry in the colormap.
* ind2rgb.m: Change %!tests to accept an indexed image with colors below the
first entry in the colormap.
* ind2x.m: Change input validation to accept all floating point images with integer
indices. Issue a warning if any of the indices are below the first entry in the
colormap. Map all color indices below the first entry to the first color in the
colormap.
