More defined way to alter background behind globe

[andrewhoyer]

Currently, the way to define what color is behind the globe is:

// Set the globe's view background
[globeViewC.view setBackgroundColor:[UIColor clearColor]];

// Set the background color for the globe
globeViewC.clearColor = [UIColor clearColor];

This works for all cases except clearColor, because the WhirlyKitEAGLView view is a subview of globeViewC.view and seems to be defaulting to black. Finding and setting that view's background color works, but doesn't feel like a solid solution.

Could there be a single function of the WhirlyGlobeViewController that sets all three of these at once, perhaps:

[globeViewC setBackgroundColor:[UIColor clearColor]];

After that the code could specifically set colors as needed for flexibility.

The other option is providing access to the WhirlyKitEAGLView via the WhirlyGlobeViewController, and letting the developer set each one individually:

[globeViewC.glview setBackgroundColor:[UIColor clearColor]];

Thanks,
Andrew

Fixed in 2.2. ClearColor will look at the color and if the alpha is less than full, it will set the two background to [UIColor clearColor]
