// Purpose: Returns the correct toss velocity to throw a given object at a point.
// Input : pEntity - The entity that is throwing the object.
// vecSpot1 - The point from which the object is being thrown.
// vecSpot2 - The point TO which the object is being thrown.
// flHeightMaxRatio - A scale factor indicating the maximum ratio of height
// to total throw distance, measured from the higher of the two endpoints to
// the apex. -1 indicates that there is no maximum.
// flGravityAdj - Scale factor for gravity - should match the gravity scale
// that the object will use in midair.
// bRandomize - when true, introduces a little fudge to the throw
// Output : Velocity to throw the object with.
