Install a new video driver.
Source position: videoh.inc line 121
| function SetVideoDriver( | 
| const Driver: TVideoDriver | 
| ):Boolean; | 
SetVideoDriver sets the videodriver to be used to Driver. If the current videodriver is initialized (after a call to InitVideo) then it does nothing and returns False.
A new driver can only be installed if the previous driver was not yet activated (i.e. before a call to InitVideo) or after it was deactivated (i.e after a call to DoneVideo).
For more information about installing a videodriver, see viddriver.
For an example, see the section on writing a custom video driver.
If the current driver is initialized, then False is returned.
