- * Note also that the viewfax decoder does not check for
- * running off the end of the input data buffer.  This is
- * possible for G3-encoded data because it prescans the input
- * data to count EOL markers, but can cause problems for G4
- * data.  In any event, we don't prescan and must watch for
- * running out of data since we can't permit the library to
- * scan past the end of the input data buffer.
- *
- * Finally, note that we must handle remaindered data at the end
- * of a strip specially.  The coder asks for a fixed number of
- * bits when scanning for the next code.  This may be more bits
- * than are actually present in the data stream.  If we appear
- * to run out of data but still have some number of valid bits
- * remaining then we makeup the requested amount with zeros and
- * return successfully.  If the returned data is incorrect then
