+ * fracviewer.h [from agviewer.h (version 1.0)]
+ *
+ * AGV: a glut viewer. Routines for viewing a 3d scene w/ glut
+ *
+ * The two view movement modes are POLAR and FLYING. Both move the eye, NOT
+ * THE OBJECT. You can never be upside down or twisted (roll) in either mode.
+ *
+ * A nice addition would be an examiner type trackball mode where you are
+ * moving the object and so could see it from any angle. Also less restricted
+ * flying and polar modes (fly upside down, do rolls, etc.).
+ *
+ * Controls for Polar are just left and middle buttons -- for flying it's
+ * those plus 0-9 number keys and +/- for speed adjustment.
+ *
+ * See agv_example.c and agviewer.c for more info. Probably want to make
+ * a copy of these and then edit for each program. This isn't meant to be
+ * a library, just something to graft onto your own programs.
+ *
+ * I welcome any feedback or improved versions.

+ * registers mouse, motion, and keyboard handlers for that window (see below).
+ *
+ * allowidle is 1 or 0 depnding on whether you will let AGV install
+ * and uninstall an idle function. 0 means you will not let it (because
+ * you will be having your own idle function). In this case it is your
+ * responsibility to put a statement like:
+ *
+ * if (agvMoving)
+ * agvMove();
+ *
+ * at the end of your idle function, to let AGV update the viewpoint if it
+ * is moving.
+ *
+ * If allowidle is 1 it means AGV will install its own idle which
+ * will update the viewpoint as needed and send glutPostRedisplay() to the
+ * window which was current when agvInit() was called.
+ *
+ * agvSetIdleAllow changes this value so you can let AGV install its idle
+ * when your idle isn't installed.
