Description:
------------
Working on another issue with getColor, I just notice :

From code
/* {{{ proto array GmagickPixel::getColor([boolean as_array = false, normalise_array = false])
	Returns the color of the pixel
*/

But second option (normalise_array) is not accepted.

Trivial attached path fix this minor issue

Test script:
---------------
php -r '$color = "rgb(255,255,255)"; $pixel = new GmagickPixel($color); echo $pixel->getColor(true, true);'

Expected result:
----------------
array(3) {
  'r' =>
  double(1)
  'g' =>
  double(1)
  'b' =>
  double(1)
}


Actual result:
--------------
Warning: GmagickPixel::getcolor() expects at most 1 parameter, 2 given in Command line code on line 1
