Log Message:
Update GraphicsMagick to 1.3.2.

1.3.2 (November 29, 2008)
=========================

Security Fixes:

  * None.

Bug fixes:

  * -roll was failing for colormapped images.

  * VID: Memory leak fix.

  * PREVIEW: Solarize parameter was wrong.

  * Delegates previously using 'spawn' needed an ampersand so that
    starting the child process does not hang the GUI.

Feature improvements:

  * +profile now supports an exclusion syntax.  For example ``+profile
    '!icm,*'`` removes all of the profiles except for the ICM profile.
    The new syntax also allows multiple profiles to be listed at once.

Performance Improvements:

  * AdaptiveThreshold, Blur, Convolve, and MotionBlur no longer
    process the opacity channel unless the image has one.
