Uniform Snapshot Camera-Themed Icons [1]
Bug Number: n/a
Release notes (y/n): Yes
For Release Nums: 7.1

RiverWare 7.0 and prior versions had inconsistent graphical "motifs" to 
refer to Snapshot-object-related functions and objects -- making use of 
essentially two, unrelated "camera" icons.  New icons have been created 
such that a new 24x24 pixel "Snapshot Manager" icon is used within the 
Snapshot-Object (special Data Object) SimObj icons.

The old and new icons are illustrated on this webpage:

    http://cadswes2.colorado.edu/~philw/2017/Icons/NewSnapshotIcons.html

This shows both an original Snapshot Manager icon with a heavy outline, and 
a revised one with a lighter outline.  The heaver-outline variant worked well 
inside the Snapshot Object icons, but was too heavy for the standalone camera 
icon.

In the course of this development, it was discovered that the (old) Scenario 
Manager is still using binary (in source) icon image data (not even XPM -- 
actual hex data in C++ source).  Only the implementation of the "Snapshot 
Manager" icon was replaced with the RwQPixmap24::camera1 icon.  (The normal 
way to define RiverWare icons is with actual graphics files bound to RiverWare 
using Qt's resource compiler).
