I was reading about the picture-related calls (OpenPicture, ClosePicture, etc.)
in Inside Macintosh Volume I the other day.  The description of OpenPicture
said that if the grafPort's clipRect is set to the default arbitrarily-large
clipping rectangle when a picture is opened, there may be problems later when
the picture is drawn; it may happen that nothing appears.

I found all this very obscure.  Can someone (a) tell me why one can't use the
default clipRect, and (b) post or send a code fragment (C or Pascal) that shows
me everything I am supposed to do when I create a picture and when I draw the
picture?

Thank you for your support.
