[IDV #NBG-538017]: background map disappears when adding image from drawing control

> If I load in a background image (e.g. the Blue Marble) and then add an
> image using the drawing control, the background image disappears. I'm
> guessing that there is a conflict between the ScalarMaps of the drawing
> control image and the data and/or maps for the background image. It
> could be that the overlay image is adding alpha and that is not set or
> set to transparent in the background image. Steps to reproduce this:
>
> - Start the IDV
> - Click on the world icon in the toolbar to load in the blue marble map
> (or select Displays->Maps and Backgrounds->Add Background Image)
> - Click on the pencil icon in the toolbar (or select
> Displays->Special->Drawing Control)
> - Click on the Create Image button (9th icon in Shapes)
> - Add in an image from the dialog (mine is attached).
