At least on my system floor() and log10() return double, so the other
arguments to Clamp() and ClampDn() didn't match anymore, now being float
instead of double.
I replaced the calls to log10f() and floorf() to avoid any ambiguities.
This was a _ton_ of changes, made 15 years ago, so there are probably some
problems to work out still.
Among others: Engine/Base/Stream.* was mostly abandoned and will need to be
re-ported.
Still, this is a pretty good start, and probably holds a world record for
lines of changes or something. :)
