Using this function you can set the FOV of any camera using two angles for x and y.

It is important to understand the parameters passed into this function:

Camnum - Number of the camera you wish to alter the FOV for
XAngle# - The X Angle (Horizontal) that you want the FOV to be changed to
YAngle# - The Y Angle (Vertical) that you want the FOV to be changed to
DX# - The Width of the camera's resolution (Or width of a plane that the camera's image is being textured on to)
DY# - The Height of the camera's resolution (Or height of a plane that the camera's image is being textured on to)
D# - This is the "Near" value of the camera's range, defaulted at 1 or changed by the function "Set Camera Range"

Using the parameters, the "Set Camera FOV" and "Set Camera Aspect" functions are used together to provide the appearance of a new FOV that is based upon two different (or same, even though it would be pointless, since the "Set Camera FOV" function will do that anyway) angles.
