As a followup, the Moz team reported back to me that the gamma was 
stored inccorrectly in the file.  They claimed that the stored gamma was 
2.2, and it should have been 1.0/2.2

I tested this, using PNGCrush to replace the gamma of an image created 
with the 3.7 beta with .4545, and the image displayed correctly in both 
Firefox and the Explorer preview ("Windows Picture and Fax Viewer").

Is this a valid statement, that the 3.7 Beta writes the gamma wrong, or 
is the Mozilla team wrong in their interpretation of the Gamma issue?
