The Size`control channel`allows you to change an actors size throughout
an animation.  For standard objects (other than the`camera`), the physical
size of the actor is adjusted.  When the size`control channel`is used for
the`camera`, the camera's focal length is adjusted.  This allows you to
create different`zoom`to wide angle lens effects.  The sizing info
requester allows you to set:

Start\End Frame
Start\End Frame sets the range of frames over which the size values will
take effect.

End Frame Size Values
End Frame Size Values represent the X,Y and Z scaling values for the
actor's axis at the end of the sizing`timeline`.  To have an actor's size
change over a series of frames you must add two separate size`timelines`.
Additionally, you must have two separate timelines for the actor 
`control channel`.  For instance, for a 30 frame animation where you want
an object to have a different starting and ending size you would add one
size timeline at the first frame and a second size timeline that extends
from frame two thru 30.  You would do the same on the actor timeline by
adding the actor on frame 1 and again from frames 2 thru 30 (the transition
frame count in the object file info requester for the actor, should be set
to 28; total animation frames minus 2).

When size is used with the`camera`, the focal length is adjusted.  Only
the X and Y settings will take effect.  The Y size value represents the
distance from the`camera`to the focal point.  The ratio between X and Y
determines the actual focal length.  A normal focal length is set when the
X value is half of the Y value.  Setting the X value larger, creates a
wider angle (lens view).  A smaller X value, creates a telephoto lens view.
