Base GL viewer object - used by both standalone and embedded (in pad) GL.

Contains core viewer objects :

GL scene - collection of main drawn objects - see TGLStdScene Cameras (fXyzzCamera) - ortho and perspective cameras - see TGLCamera Clipping (fClipXyzz) - collection of clip objects - see TGLClip Manipulators (fXyzzManip) - collection of manipulators - see TGLManip

It maintains the current active draw styles, clipping object, manipulator, camera etc.

TGLViewer is 'GUI free' in that it does not derive from any ROOT GUI TGFrame etc - see TGLSAViewer for this. However it contains GUI GUI style methods HandleButton() etc to which GUI events can be directed from standalone frame or embedding pad to perform interaction.

Also, the TGLWidget needs to be created externally. It is not owned by the viewer.

For embedded (pad) GL this viewer is created directly by plugin manager. For standalone the derived TGLSAViewer is.

		Float_t	pixel_object_scale = `0`
	)

Save current image in various formats (gif, gif+, jpg, png).

'gif+' will append image to an existing file (animated gif). Frame-Buffer-Object is used for capturing of the image - OpenGL 1.5 is required. The viewer window does not have to be visible at all. Returns false if something obvious goes wrong, true otherwise.

pixel_object_scale is used to scale (as much as possible) the objects whose representation size is pixel based (point-sizes, line-widths, bitmap/pixmap font-sizes). If set to 0 (default) no scaling is applied.
