rgdAnalyze extracts style data mismatches from Mozilla layout
regression test verifications into a more human-readable format.

It's a short Perl script that will transform an intractable
frame style data mismatch: |null attr|0 0 3 3 12632256 0 0 1

You can then easily find the name of the style property by
looking in the DumpRegressionData function in nsStyleContext.cpp.
([2,1] is Color.mColor)
It does this for each test result in the file and then
prints a list of all style data mismatches in the
verification *without duplicates* so you can quickly tell
which properties your changes have affected.

Thought you might find it useful. I did. *shrug*
