[Bf-committers] premul/key alpha display

Hi Ton, all,

Currently, the uv/image editor display images as having premul alpha, 
but image textures usually have key alpha. I would propose to add a flag 
to the image datablock that sets premul/key display, editable in the 
image properties panel.

For regular images, this flag would be set to key by default. For render 
result and viewer node images, the sky/premul/key render setting could 
be used. But this setting is not necessarily accurate with a compositer 
and sequencer inbetween. Not sure what the conventions are, and what 
would be right thing to do here?
