[vtkusers] Resource Leak with VTK + BCB6 (vtkTimerLog)

[Xianjin Yang]

Here is the relevant VTK source code the "Leak" error message points to

// Allocate timing table with MaxEntries elements.
void vtkTimerLog::AllocateLog()
{
  if (vtkTimerLog::TimerLog != NULL)
    {
    delete [] vtkTimerLog::TimerLog;
    }
  vtkTimerLog::TimerLog = new vtkTimerLogEntry[vtkTimerLog::MaxEntries];   <====
This Line
}


void vtkTimerLog::MarkStartEvent(const char *event)
{
  if (! vtkTimerLog::Logging)
    { // Maybe we should still change the Indent ...
    return;
    }

  vtkTimerLog::MarkEvent(event);   <======= This Line
  ++vtkTimerLog::Indent;
}

void vtkOpenGLPolyDataMapper::RenderPiece(vtkRenderer *ren, vtkActor *act)
{
    ...

    if (!this->ImmediateModeRendering && 
        !this->GetGlobalImmediateModeRendering())
      {
      vtkTimerLog::MarkStartEvent("Building display list");   <==== This Line
      this->ReleaseGraphicsResources(ren->GetRenderWindow());
      this->LastWindow = ren->GetRenderWindow();
   ...

}

Same problem on linux:
