Log Message:
when doing host blits, let the fifo drain every now and then. Apparently even
a relatively slow CPU can overload a relatively fast Rage 128 in some
circumstances.
This cures weird artifacts seen when scrolling lots and lots of text very
fast. Why this only showed up with glyph cacheing which should reduce the
frequency of host blits isn't quite clear though.
