Subject: [PATCH] Enable clearDepthBuffer for Pokemon Snap.

Fixed Pokemon Snap Oak's check does not work #777 again

Note: this game is a mistery. I don't understand,
why clearing of depth buffer via drawRecs breaks Oak's check.
Actually, the problem causes rendering to color buffer corresponding to that depth buffer.
Need to investigate, why.
