[PATCH] Add glretrace option '--snapshot-format=MD5' that allow write image MD5 to a text format file.

[Meng, Mengmeng]

Hi, I do a test comparing MD5 with PNG,
Open Arena at 800x600 on IVB 
MD5:  Rendered 3435 frames in 478.734 secs, average of 7.17518 fps  md5.file 4K
PNG:  Rendered 3435 frames in 143.251 secs, average of 23.9789 fps   pnp.file 1.7G

But there is a verification problem. It means that with the same driver, MD5s are not all same between two tests. E.g. there are ~263 different frames in 3435 frames
So we may consider "a threshold value"?



Thanks,
Meng

Alex,

Sure, we can all happily agree about having clean and tidy patches for consideration.
