Fix sprite blitter choice logic
While we're asking if there are any color space xform steps to do,
let's look at all 5 of them, including whether we need to unpremul or
premul. The sprite blitter paths this logic guards can't handle
any change in color space _or_ alpha type, so this is a perfect fit.
Without this fix, we'd happily draw premul into unpremul using memcpy().
(Unpremul -> premul was already guarded by the check with my new note.)
