"disable incremental display while loading from URL"

Patch:    ivtools-020731-johnston-061
For:      ivtools-1.0.4
Author:   [email protected]
Subject:  disable incremental display while loading from URL
Requires: 

This is an intermediate patch to ivtools-1.0.4.  To apply, cd to the
top-level directory of the ivtools source tree (the directory with src
and config subdirs), and apply like this:

	patch -p0 <ThisFile

Summary of Changes:

- disable incremental display while incrementally loading from a URL.
A placeholder raster still gets inserted before the connection is
established, and the rest of the download and display is asynchronous,
which avoids hanging on a net connection.
