I'm actually tempted to avoid  the entire issue and just require that 
the user provide a QAbstractTexture object that contains a cubemap 
texture target. It's trivial  to do this with a dds file already but we 
can add a convenience helper if  you want to be able to build a cubemap 
texture object from a set of 2D images. That will make the API minimal 
and complete by delegating the complexity to other classes such as 

Thanks for the feedback.
