Render Mode Example.

The point of this demo is to show that for certain kinds of 3d applications that don't have animation, for example a map viewer, you can set the client's render mode to RENDERMODE_ON_DEMAND which will render the 3d one time and then stop rendering. This has the advantage of not wasting CPU cycles rendering something that does not change over and over.

The background changes color each time the scene is rendered. The sample should start with the scene being constantly rendered but click RENDERMODE_ON_DEMAND and you'll see it rendered only when it needs to be as determined by the sample.

RENDERMODE_CONTINUOUS (draw as often as possible)
RENDERMODE_ON_DEMAND (draw once then as the OS requests it like when a window is uncovered)
