Description:
------------
Tryed Imagick::quantizeImage() which needs an Imagick::Colorspace as second argument. Strange thing is that every colorspace i choose, the return keys of an array are still r/g/b  instead of colorspace named keys like h/s/b or l/a/b for example when reading the colormap with Imagick::getColors().

Reproduce code:
---------------
// this->image comes from the class constructor
// -> $this->image = new Imagick($image);
function getColors()
{	
    $this->image->quantizeImage( 30, Imagick::COLORSPACE_HSB, 0, false, false );
    $this->image->uniqueImageColors();

    $it = $this->image->getPixelIterator();
    $it->resetIterator();

    while( $row = $it->getNextIteratorRow() )
    {
	    foreach( $row as $pixel ) $this->colors[] = $pixel->getColor();
    }

}



Expected result:
----------------
Expected different return keys when changing the colorspace constant. Unfortunately i don't know which stack expresses what if the colorspace isn't RGB. Either i don't know if the problem is in quantizeImage() or getColors().
