Branding PNG Downloads

Users can download graphs as PNG images. You can apply some branding to this format:

You can add some text (such as a copyright statement).
You can specify the filename of the PNG (or choose to have this automatically generated).
You can specify the size of the PNG (or choose to have this set automatically based on the current size of the user's browser window).

To change these settings, edit <tomcat_home>\webapps\webapi\scripts\sw2-charts\sw2-chart-export-options.js.
