Apple's Human Interface Notes discuss the appropriate positioning of
alerts and dialogs.  In summary, you place the dialog such that it is
centered left-to-right, and placed top-to-bottom such that 1/3 of the
remaining Y-axis space on the screen (excluding what's taken up by the
dialog itself) is above the dialog.

This is pretty easy to accomplish; somebody already posted a method
for twiddling with the dialog's definition before you display it, using
DialogTHndl's, etc.
