+// *****************************************************************************
+//
+// CLASS DESCRIPTION (MPxGlBuffer)
+//
+//  MPxGlBuffer allows the user to create OpenGL buffers that Maya
+//	can draw into.  The base class as is defined will create a hardware
+//	accellerated off-screen buffer for use on SGI hardware.
+//
+//  To create a custom buffer, derive from this class and override at
+//	least the open, close, drawable, and context classes.  The customized
+//	buffer may also require a constructor and destructor to initialize and
+//	free its storage correctly.
