Philipp Oeser 82f51fe913 Fix T77356: Texture Preview not taking alpha into account
Since rB329b4c3363e4 a texture preview is not rendered through the
preview.blend and a renderengine anymore [unlike materials etc.]

Alpha wasnt handled in that commit, take that into account now.

sidenote: not sure if we should be looking into drawing alpha with a
checkerboard in the background for texture previews (see texture
previews elsewhere)?

sidenote 2: might also be good to document where the "calculate" and
"invert" alpha options are still used? [looks a bit inconsistent:
compositor uses it, Image Editor as well as Render Engines dont?]
