Does anyone know what this extension string does? I wasn't sure if I should make
it "true" or "disjoint_timer_query_EXT". Technically the other
GetQueryObjectuivEXT are not solely for occlusion_query_EXT also, does that
field support lists? This function is special because it is supported by
disjoint_timer_query_EXT but not occlusion_query_EXT.
