Was ist die maximale Grösse für Kullisen-Hintergründe?

I don't understand why it is needed to load a static background image. Why I can not set optional a scene size by setting widht, height and background color (= clear screen color)?

thought about it, too. Even if the engine then creates an image to display out of the parameters given or just filling the screen with the color at runtime (dont know whats easier to implement on the internal site if the engine) . 
Its not annoying for me on the scenes section though, because in 99% of the cases I will add a background with the size of the scene. More important would this feature be in the interface section where i need to create invisible background images...

It's probably tied into some old method the engine had to use years ago that's so ingrained now that it can't be ripped out & replaced, like some of the other old antiquated features (the not so flexible/dynamic dialog system springs instantly to mind).
