Description:
------------
In RecolorImage, the underlying call is:

1394: status = MagickRecolorImage(intern->magick_wand, 
num_elements, array);

However, MagickRecolorImage expects the 2nd parameter to be 
the number of *rows* in the matrix, i.e. the square root of 
the number of elements in the array. This causes ImageMagick 
to read off the end of the array and segfault and/or cause 
garbage transformations.

Reproduce code:
---------------
image.recolorImage(array(1.0, 0.0, 0.0, 1.0));

Expected result:
----------------
The image will not be perturbed. The 2x2 matrix given is a 
subset of the identity matrix.

Actual result:
--------------
An arbitrary transformation occurs and/or php crashes.
