[ROOT] TPGON and OpenGL - X3D and Shift interface

Hi all,

TPGON and OpenGL - X3D:
-----------------------
There seems to be a problem when trying to draw a TPGON in OpenGL or
X3D.  It gets SIGSEV unless I set the visibility `0'.  The script and a
log are attached.  

Missing libOIV?: 
----------------

In the default `etc/root/system.rootrc' there's the line 

	+Plugin.TVirtualViewer3D:   oiv TViewerOIV    OIV "TViewerOIV(TVirtualPad*)"

However, the library `libOIV' isn't build, and there's no dictionary
created for the `TViewerOIV' class, so this line is (double)
meaningless.

SHIFT:
------

Currently, the `configure' script checks to find `rfio_api.h'.  However,
in SHIFT 1.10.3.5 (the most recent I could find at
`/afs/cern.ch/asis/src/SHIFT/') no such file exists. Hence `configure'
complains.   The closest file I could find was `<shift/rfio.h>'.  I ask
`configure' to look for that file instead I get the following warning
from `configure':

	### Found old version of libshift, please uprade to >=1.5.2

Now, 1.10.3.5 is larger than 1.5.2, so should `configure' accept this
header?   

I looked in the `configure' script, and saw that it looks for
`rfio_fchmod' in the header file.   In SHIFT 1.10.3.5 there's no such
function or symbol.  The function `rfio_chmod' is there, however. 

It's kind of odd to test for `rfio_fchmod' as it isn't used in the RFIO
interface at all.   A simple grep and sed gave me 

        > grep 'rfio_' rfio/src/*  | \
            sed -e '/\/\//d' \
        	-e 's/\([^:]*\):.*\(rfio_[a-zA-Z0-9_]*\).*/\1: \2/g' | \
           sort -u
        rfio/src/TCastorFile.cxx: rfio_HsmIf_IsHsmFile
        rfio/src/TCastorFile.cxx: rfio_HsmIf_reqtoput
        rfio/src/TCastorFile.cxx: rfio_parse
        rfio/src/TRFIOFile.cxx: rfio_access
        rfio/src/TRFIOFile.cxx: rfio_close
        rfio/src/TRFIOFile.cxx: rfio_closedir
        rfio/src/TRFIOFile.cxx: rfio_errno
        rfio/src/TRFIOFile.cxx: rfio_fstat
        rfio/src/TRFIOFile.cxx: rfio_lseek
        rfio/src/TRFIOFile.cxx: rfio_mkdir
        rfio/src/TRFIOFile.cxx: rfio_open
        rfio/src/TRFIOFile.cxx: rfio_opendir
        rfio/src/TRFIOFile.cxx: rfio_parse
        rfio/src/TRFIOFile.cxx: rfio_perror
        rfio/src/TRFIOFile.cxx: rfio_read
        rfio/src/TRFIOFile.cxx: rfio_readdir
        rfio/src/TRFIOFile.cxx: rfio_serror
        rfio/src/TRFIOFile.cxx: rfio_stat
        rfio/src/TRFIOFile.cxx: rfio_unlink
        rfio/src/TRFIOFile.cxx: rfio_write
        
which are then the `rfio_' symbols referenced in the SHIFT interface. 
 
I'm using:

			with OpenGL and OpenIV. 
	OS:		Debian GNU/Linux unstable `sid'
