+I provide composition ability of multiple `BlBackground`.
 I am useful when an Element should have both paint and image backgrounds.
 
 Note: composed backgrounds are rendered in the same order they are defined in a composition. So for example if I was created as follows:

 	BlImageBackground image: PolymorphSystemSettings pharoLogoForm
 } 
+```
