-  * Add x:silent option to prevent beeps when reading the X image format.
-  * Recognize TTF for GetMagicInfo().
-  * Ensure the +set option deletes the image artifact.

+  * Properly scale color components of the PNG bKGD chunk.
   * Prevent MNG divide by zero in calculation of frame_timeout.  Set
     both frame_delay and frame_timeout to infinite when ticks_per_second
     is zero, as required by the MNG spec.

   * Third Re-write of MorphologyApply() to better handle compound methods.
   * Implemented  -set option:morphology:compose for merging results of
     multiple kernels. "None" means re-iterate results with next kernel.
