The texture2D() happens in each branch, so we may as well do it as early
as possible and hide some of its latency in the branching instructions.
Moving it outside the (uniform) control flow reduces the number of
instructions in the fs_source shader from 64 to 46 and in the
set_alpha_source shader from 69 to 47 on Haswell.

By dropping the unconditional logic op disable at the end of
rendering, this fixes GL errors being thrown in GLES2 contexts (which
don't have logic ops). On desktop, this also means a little less
overhead per draw call from taking one less trip through the
glEnable/glDisable switch statement of doom in Mesa.
The exchange here is that we end up taking a trip through it in the
XV, Render, and gradient-generation paths. If the glEnable() is
actually costly, we should probably cache our logic op state in our
screen, since there's no way the GL could make that switch statement
as cheap as the caller caching it would be.
