I have made some amendments to the GDML Import, and have implemented new
functionality to the python implementation for the GDML Export.

fixes in TGButton and TGButtonGroup classes related to double emitted
signals (bug #23011).
In addition are follow-up changes in different GUI classes where a
work-around was used by connecting the slots to the signals Released or
Pressed instead of Clicked.

  the bounding is computed taking care of the text angle. When it is false
  (default), the horizontal bounding box is computed.

This patch cleans up the AFS code and adds the possibility to instantiate
a token from any ROOT session.

There is a new class, TAFS, wrapper around a few C functions to create,
verify and destroy a token. This new code is available as a plugin library
libAFSAuth. In a ROOT session you can do

            root[] TAFS::Init()

to initialize a token in the default domain. You will be prompted for the
password. This creates an instance of TAFS and saves a pointer to it in
the global gAFS. Then

            root[] gAFS->Verify()

shows the seconds left to token expiration.
The C function are in AFSAuth.cxx; AFSAuth.o is linked to rpdutils.o so
that the same code is used there.
In PROOF, pmain.cxx loads libAFSAuth using the plugin manager when it
is told that AFS credentials are available (in the form of a file in the
sandbox).

is added to TFile:
Int_t TFile::SaveObjectAs(const TObject *obj, const char *filename, Option_t * /*option*/)
   // Save object in filename (static function)
   // if filename is null or "", a file with "objectname.root" is created.
   // The name of the key is the object name.
   // If the operation is successful, it returns the number of bytes written to the file
   // otherwise it returns 0.

This function wil be typically called via CINT from places where time is not critical.

  virtual Int_t TBuffer::GetVersionOwner() const
It returns the version number of the buffer owner. In case of TBufferFile,
it returns the file version number.

This new function is introduced to further reduce the dependencies on the I/O system.

  GetBoundingBox were not correct. The following macro can be used as test
  case:

  {
     TCanvas *c = new TCanvas("c","c",600,600);
     UInt_t w,h;

     TLatex *l1;
     l1 = new TLatex(0.,0.2,"C(x) = #int^{x}_{0}cos(#frac{#pi}{2}t^{2})dt");
     l1->SetTextFont(42); l1->SetTextSize(0.03);
     l1->GetBoundingBox(w, h);
     printf(">>> w = %d h = %d <<<\n",w,h);

     TLatex *l2;
     l2 = new TLatex(0.,0.6,"C(x) = #int^{x}_{0}cos(#frac{#pi}{2}t^{2})dt");
     l2->SetTextFont(43); l2->SetTextSize(18);
     l2->GetBoundingBox(w, h);
     printf(">>> w = %d h = %d <<<\n",w,h);
  }

  The first TLatex is drawn with a size in NDC and the second with a size in
  pixels.
