Log Message:
Update GraphicsMagick to 1.1.11.

Significant changes associated with GraphicsMagick 1.1.11 (released September \ 
23, 2007)

  Bugs Fixed:

    o BMP: Support large files.

    o DIB: Support large files.

    o PNG: Fix depth handling with 16-bit PNG files in the Q8 build.

    o SUN: Properly report image depth.

    o TIFF: Endian option (-endian) now controls TIFF byte endian order
      rather than bit fill order.

    o DCM, DIB, XBM, XCF, XWD: Eliminate integer overflow vulnerability
      (IDefense 09.19.07).

    o HSL colorspace transform: Avoid optimization bug noticed on Opteron
      with GCC.

    o HWB colorspace transform: Avoid optimization bug noticed on Opteron
      with GCC.

    o RGBTransformImage()/TransformRGBImage(): Was using HWB colorspace
      when HSL was requested.

    o Successfully reads files with names like 'file[123]'.

    o 'gm display': No longer rely on isatty() to determine if input is
      from a pipe (use 'gm display -' to display an image read from a pipe).

  Feature Improvements:

    o 'identify +ping' forces the pixels to be read (similar to GM 1.2).

    o 'gm -version' now indicates if build supports "Large Memory" \ 
(i.e. 64-bit).

    o TIFF: Use '-define tiff:fill-order={msb2lsb|lsb2msb}' to control
      TIFF bit fill order.

  Performance Improvements:

    o No longer bogs down if a directory contains hundreds of thousands of
      files and the filename looks like a wildcard specification.
