SuperCard perhaps?  IIRC it was the only xTalk at the time (until Sybase 
Gain Momentum came out later for Unix, followed by MetaCard and others) 
that provided scriptable vector graphics.

I believe all versions of HyperCard only natively supported bitmaps, and 
only two per card, one at the background level and one on the card.
