Description:
------------
I had been using Imagick 3.1.2 version, and I see that there is some bug in setColorspace function. The output of this function is always the same image, irrespective of the Colorspace constant I use.

Test script:
---------------
$img = new Imagick();
$img->setColorspace(imagick::COLOSPACE_GRAY);
$img->readImage('i.jpg');
$img->writeImage('o.jpg');
$img->destroy();

Expected result:
----------------
I expect to get a full grayscale image as output, and yet I do not get so.

Not a bug.

The correct function to use is transformImageColorspace. I think setColorspace is for new images created in memory e.g. with newPseudoImage
