Subject: Add "apitrace diff-images" command
X-Git-Url: https://git.cworth.org/git?p=apitrace;a=commitdiff_plain;h=1cbf9182d7158859160ba8ef8405fad7390644b3

Add "apitrace diff-images" command

Which simply calls out to the existing snapdiff.py script, (notably,
it also passes "apitrace diff-images --help" to snapdiff.py as well).
