Many things on the IBM use straight bit-blits, while on the Macs they typically
use PICT's.  The game 'crazy cars' work right... really right   So does the
OIDS demo.  I try not to compare individual operations on the Mac and IBM
because the approaches vary so widely.
For example, many program bit blit and otherwise take shortcuts on the IBM,
but when a new video card comes out, they stop working.  The code that slows
down quickdraw also makes things like Mac II compatibility with Pluses/SEs
possible.
