- Change migration-in rule slightly: previously, if your score was less

    than the max, it was bumped, and then if you were above the threshhold
    you got moved in. Instead, do the above-threshhold check separate from
    score starting out less than max. While this will likely make thrashing
    cases worse, I hope it will fix some issues with long term performance
    (think of an xcompmgr with a backbuffer it's doing only accelerated
    operations to. If some new pixmap comes in and bumps it out, even once,
    it will never get a chance to re-migrate because its score will be
    maxed). Change migration-out to be the same way for symmetry, though it
    shouldn't ever affect anything.
- Fix a lot of debugging output, both in terms of printing quality, and
    completeness. The fallback debugging covers a lot more now, pointing
    out new areas for improvement. Debugging toggles are now centralized in
    exaPriv.h.
