Comments
 
The next call to the following SaveScreen function uses the given swap drive
letter to open the swap file, if needed. Failure to call this function at
least once before SaveScreen may result in a failure to switch the video
context. This drive and path information is stored as a static value and
need not be set before every call to SaveScreen.
