TextFile

A DVI window will have the following operations:

Open: Filename X Window -> DVIW # errormessage
   Opens a dvi window viewing a particular file.
Close: DVIW -> Window
   Closes a dvi window.  The text on the window is unaffected.  Each
   time a showpage operation is done, the DVIW checks whether the file
   has changed; if it has, the old file is closed and the new file is
   opened.
Showpage: DVIW X pagenum X xscroll X yscroll -> realpage
   Attempts to show page pagenum of the file associated with DVIW.
   Realpage will be different from pagenum if pagenum is not positive
   or the document does not have that many pages.

For now, we will forbid having several of these open for one process
at once.  However, it should be possible to open and close several
DVIW's in sequence without accumulating garbage in the address space.
The DVIW's need the following state information:
   Window
   File descriptor
   Cpagep: Pointer to start of current page in the file
   Ppagep: Pointer to previous page in the file
   Pagenum: Current page number in the file

The routines used to display the file will be determined at load time.
The names of the routines is a historical phenomenon not documented
here.
