26    *              Ogre::Root::getSingletonPtr()->initialise(false) and retrieved by calling
27    *              "Ogre::Root::getSingletonPtr()->getAutoCreatedWindow()", or the manually created
28    *              window from calling "mRoot->createRenderWindow()".
29    *  gridSize:      The magnification factor.  A 2 will create a 2x2 grid, doubling the size of the
30                screenshot.  A 3 will create a 3x3 grid, tripling the size of the screenshot.
31    *  fileExtension:    The extension of the screenshot file name, hence the type of graphics file to generate.
32    *              To generate "MyScreenshot.png" this parameter would contain ".png".
