Sets a new sight cone (field of vision) for perspective views.
(Applicable in solid module only.)

         1. (NUM) new sight cone for perspective views (1-170 deg.)<70>

Description
This command sets the angle of the field (cone) of vision when viewing
perspectives.  It is analogous to the angle of a camera lens; the wider the
angle, the more may be included in the view but the distortion will also be
greater.

The model will be drawn according to the new sight cone in the current
display mode.
