Hi,

I have a question about pfESkyMode() called with PFES_BUFFER_CLEAR
set to PFES_SKY_CLEAR. The man page for pfESkyMode() says that this
mode will "Draw the sky horizon and clear the screen below the
edge of the horizon." Will the Z-buffer also be cleared below the
horizon? In my application, the Z-buffer doesn't seemed to be getting
cleared. Does anyone have any suggestion about how one might clear the
Z-buffer below the horizon when using PFES_SKY_CLEAR assuming that
PFES_SKY_CLEAR does not?

               Thanks,
