proposed fix

Ok i think i found the problem. I believe RealizePalette was sometimes wrongly
copying back buffer surface to screen. The check must probably be replaced with
== ddraw_primary as in e.g. UnlockRect. That fixes gamma options flicker for me
(and  that's the only flicker i saw).

Please test this fix and let me know if it fixes all issues.
