Limit 3D tracers to units in view about arcmt HOT 2 CLOSED

With the new FPS fix this may not be needed anymore. Before the FPS was getting bottle necked by the onFrame event but now it skips 4 frames and the life of a projectile is shorter so each fire event has enough time to process.

Algorithm for this could be to calculate the position boundaries using the camera attributes. For example if we know the position and direction of the camera, we know where the cone of view is. That cone is then altered based on the current FOV setting. With an accurate cone of view, work out the world positions of top left, top right, bottom left, bottom right and then calculate the maximum radius from those positions - this then gives us the center position and radius to search for units.

However all that might be way too slow to run and we'll probably just stick with what we've got now.
