Use surfaceClip as a hint for the underlying rendertarget size

Browse Source 
TIC sizes may not be aligned to block linear dimensions whereas RT sizes are and then limited by the surface clip. By using this to determine surface size we are more likely to get a match in texture manager for any future usages.
