Message:

Added Hardware Occlusion Query Capabilities for use in dynamic flare effects, this is still a pretty static implemenation, meaning it will fail with mutltiple HOQ objects on screen, also needs some tidying up and documentation at a later point

+    //TODO: The Hardware Occlusion only works properly for a single Flare on the screen,
+    // if we have multiple strong lights it'll become way more complicated to determine how much of every object is occluded individually
+    // there's below a 100 render queue groups, so maybe we should take turns for each object to be tested, so we only have one of the objects rendered at a time
+    // obviously we shouldn't use too much of these effects anyways, since they use a lot of performance, so not sure whether it's worth implementing a solution that works for multiple lens flares on screen
