+ READ TIFF
+ Load the TIFF data from the file into memory. Return
+ a pointer to a valid DIB (or NULL for errors).
+ Uses the TIFFRGBA interface to libtiff.lib to convert
+ most file formats to a useable form. We just keep the 32 bit
+ form of the data to display, rather than optimizing for the
+ display.
+
+ Main entry points:
+
+ int ChkTIFF ( LPCTSTR lpszPath )
+ PVOID ReadTIFF ( LPCTSTR lpszPath )
+
+ RETURN
+ A valid DIB pointer for success; NULL for failure.
