    Hang and scroll up fixes

    This fixes ticket 207 by fixing the partial scrollup optimization
    in bitmap output that scrolls down the screen, the scrolls up the
    part that should not have moved.

    While testing this change however, I managed to reproduce two unlikely
    but possible deadlocks since I was rebuilding all the software on
    my computer at the time and it was under very heavy load.

    One of these issues was apparently found by Coverity and explcitly suppressed... possibly this suppressed the other as a side-effect
    as well.

    These suppressions don't work, remove them.

    Attempt the same suppression a different way.

    First attempt at fixing bug ticket 209

    Apparently new for v1.7 we're snapping to the next lower integer
    scaling on any clal to textmode()... this is bad because some
    people don't want integer scaling for various excellent reasons.

    Deal with this two ways when calling textmode() and not already
    using integer scaling:
    1) Save the previous scaling and if the stars align, just re-use
    it instead of trying to recalculate it (a fools errand after
    round-tripping through C64 for example).
    2) Otherwise, do successive estimations until we're taking steps
    of less than 0.00005 in the multiplier, then call it good. This
    gets pretty close, but can add or remove a few pixels.
