Instead of storing all block width, height and depths in their shifted
form:
block_width = 1U << block_shift;
Store them like they are provided by the emulated hardware (their
block_shift form). This way we can avoid doing the costly
Common::AlignUp operation to align texture sizes and drop CPU integer
divisions with bitwise logic (defined in Common::AlignBits).
Due to our current infrastructure, it is possible for a mipmap to be set
on as a render target before a texception of that mipmap's superset be
set afterwards. This is problematic as we rely on texture views to set
up texceptions and protecting render targets targets for 3D texture
rendering.
One simple solution is to configure framebuffers after texture setup but
this brings other problems. This solution, forces a reconfiguration of
the framebuffers after such event happens.
