02159: cubeqst: Cubequest asserts on ATI hardware w/ prescale > 1

Browse Source 
Added 1:1 fallback if surface creation fails at prescale values. Changed
prescale logic to create prescale target surfaces as ARGB for YUY2 
sources. Forced the use of render-to-texture over StretchRect for YUY2
sources.
