[Image-SIG] Does PIL ImageDraw create shape objects or stain pixels?

[James]

AFAIK, ImageDraw is a raster-based library, not object or vector
based.  So I don't think any objects are kept around, and changes
simply happen to a buffer.  I could be wrong.

That's not to say there aren't other performance issues to watch out
for.  But I don't imagine that simply drawing a ton of shapes will
overload memory in ImageDraw like it would in a lib that saves object
information.
