Original change's description:
> Respect kRectsMustMatchForMSAASrc_BlitFramebufferFlag in dst setup
> 
> Crurently, when preparing a texture for blitFramebuffer, we ignore the
> kRectsMustMatchForMSAASrc_BlitFramebufferFlag, and may attempt to
> copy from one src rect to a different dst rect.
> 
> This change updates initDescForDstCopy and setupDstTexture to allocate
> larger textures if necessary and accomodate this flags requirements.
