SL-11545, SL-11543, SL-10625

Fix emissives without normal maps clobbering the alpha output in materialF.

Modify glow size calc to get close to pre-EEP sun glow behavior (may require sky vert settings >= mid).

Make bake ignore alpha readback for Intel until we can determine why their drivers now go boom.
