#ifndef GLVIEW_H_
#define GLVIEW_H_
/* GLView: A basic OpenGL rectangle for rendering images.
This class is inherited by:
*QGLview - for Qt GUI
*OffscreenView - for offscreen rendering, in tests and from command-line
The view assumes either a Gimbal Camera (rotation,translation,distance)
or Vector Camera (eye,center/target) is being used. See Camera.h. The
cameras are not kept in sync.
QGLView only uses GimbalCamera while OffscreenView can use either one.
Some actions (showCrossHairs) only work properly on Gimbal Camera.
