Description:
------------
PHP version is actually 5.2.6
Imagick version is actually 2.2.1rc1

Reproduce code:
---------------
// opaque
$im = new Imagick();
$im->newImage(100, 100, '#CCCCCC', 'png');
$im->colorizeImage('#0000FF', 1);
header('content-type: image/png');
echo $im;

// transparent
$im = new Imagick();
$im->newImage(100, 100, '#CCCCCC', 'png');
$im->colorizeImage('#0000FF', 0);
header('content-type: image/png');
echo $im;


Expected result:
----------------
The first image should be bluish, the second one grey, since the blue should is set to complete transparency (0).

Actual result:
--------------
Both images are bluish in the same degree.

Please have a look at imagick_class.c:5679. The intern_opacity from 5675 is not processed.

Thank you for the report, and for helping us make PECL better.
