-/*  This function gets a path of a DVI, EPS, PS or PDF file and
-    produces a PNG-Thumbnail which is stored as a TQImage
-
-    The program works as follows
-
-    1. Test if file is a DVI file
-
-    2. Create a child process (1), in which the 
-       file is to be changed into a PNG
-       
-    3. Child-process (1) :
-
-    4. If file is DVI continue with 6
-    
-    5. If file is no DVI continue with 9
-
-    6. Create another child process (2), in which the DVI is
-       turned into PS using dvips
-
-    7. Parent process (2) :
-       Turn the recently created PS file into a PNG file using gs
-       
-    8. continue with 10
-
-    9. Turn the PS,PDF or EPS file into a PNG file using gs
-
-    10. Parent process (1)
-        store data in a TQImage
