sometimes SF would not process a surface resize 

this would happen when a window started with size A, was
resized to B and immediately resized to A. In this situation
the erquested and active size would be the same, and SF
would think a transaction wasn't needed.

we fix this by always comparing the requested sizes.

Also, make sure to set mRefreshPending once we're sure
we have succesfully called updateTexImage().
