This prevents computing a shift value outside of [0..31].

OpenGL modes: factor out shade factor calculation.

This also means that the "r_shadescale_unbounded 0" option will work
in Polymer (except on models).

rotatesprite calls, fixing complex HUD drawing code relying on precise
alignment of individual elements (widescreen rotatesprite is entirely
unsuitable for this purpose).
