This allows us to more easily compare sets of parameters used in our
tests. The config parameters are stuff like the red / gree / blue bits
used in an EGL config. Or particular sets of extensions or other
EGL options.
This will more easily allow us to determine when we need to use a new
EGL display instead of reusing a prior.
