[sldev] Hide geometry in Sculpted-prims

[Feilen]

That's actually a lot better of an idea, and it would be simple to 
implement: just use any basic image editor to implement the alpha and 
remove all of the black space the 3d modeler creates. If this was 
implemented it would be likely that all plugins/modelers supporting 
would also change to generate alpha instead of blackspace.
