ConditionalRendering

================================================================================

DESCRIPTION:

This sample demonstrates how to do conditional rendering based on an occlusion 

query. The NV_conditional_render extension defines two functions, 

BeginConditionalRenderNV and EndConditionalRenderNV, between which rendering 

commands may be discarded based on the results of an occlusion query. If the 

specified occlusion query returns a non-zero value, rendering commands between 

these calls are executed; otherwise, they are all discarded.
