what is a "smartglass device"?
They were originally OGL devices when OpenGL was still a going concern. Since the branching of the GL trunk code, and the snarky, retaliatory, semi-proprietarization of the version running on closed devices such as iPads and Surface tablets, that was originally called "SmartassGL," but someone thought it looked better as "SmartGLass."
I'm running a version right now.
