[webkit-dev] ImageDiff tool for gtk platform

[S Venkata Udai Kiran]

Hi all,
   I was trying to understand how the Layout tests are being done in 
Webkit. I  went through the perl code 'run-webkit-tests' and found that 
the script is using a tool name ImageDiff  
(WebKit/WebKitBuild/Release/Programs/ImageDiff) .But I could not 'find' 
that tool in WebKit folder. As I understand that ImageDiff tool is 
necessary to do a pixel level diff for test images generated.I am 
looking at running individual tests using a small shell script rather 
running all the tests at once. this will help me to know the underlying 
things.  Please help.

Thanks,
Udai.
