The landing point is noted from the grenade's cEventFX 0x96 at launch; a
translucent red circle with the explosion radius (shared ImpactRadius) is
drawn after the world's ground, under the objects, and ends when that
grenade's impact gathers its targets. Ground -> screen projection in
game/engine/worldview.h.
