Fix SW sRGB dst + LCD coverage bug.

Fix SW sRGB dst + LCD coverage bug.

We're using the linear procs for sRGB destintations
and the sRGB procs for linear destinations.  Fix that.

C.f. State32::getLCDProc(), which flags |= kDstIsSRGB_LCDFlag.
kDistIsSRGB is (1<<2) == 4, so the sRGB procs must be 4-7, not 0-3.
