It would be useful to have some references in SVN and also a tool to
diff these files, producing a hint on what's different other than pure
"cmp a b: files differ at byte X". This is done by WebKit, for
instance
Another useful idea from WebKit is the virtual dump of the render
tree. This walks the canvas, layers and objects (recursively) to
produce a textual output, that is then able to be diff'ed. This is
simpler to check and diff, also faster to run. Something like:
Evas #123 100x100:
Layer #456:
Rectangle #1 @0,0 100x100 #ffffffff clipper=NONE
pass_events=TRUE repeat_events=FALSE visible=TRUE
Image #2 @10,10 50x50 #ffffffff clipper=#1 pass_events=TRUE
repeat_events=FALSE visible=TRUE visible=TRUE border=2,2,2,2
scale_hint=STATIC file=bla key=NONE
Smart #3 @0,0 100x100 #ffffffff clipper=NONE ...
Rectangle #4 ...
Text #5...
The idea is to create virtual pointers (#1, #2...) so we can reference
them and diff the results in different runs.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
