• Snapshot can be saved in EPS, PS and XFIG vectorial format (thanks Cyril).
• Gestion of a QGLViewer pool. See QGLViewer::updateGLForAllViewers() and QGLViewer::connectSignalToAllViewers().

• QGLViewer::startScreenCoordinatesSystem() was flawed, now ok. See the screenCoordSystem example.
• The different slots (toggleDisplayFPS(), toggleDrawAxis()...) now call updateGL(). The qt bug that prevented it was patched.
• REVOLVE trackball orientation no longer depends on the mouse path.
• Vec class slightly modified (some const removed and normalize() returns a ref).

• Frame::transformOf() and similar functions to convert vectors between frames.

• QGLViewer::drawLight() polished. See the drawLight example.
• Quaternion::setFromRotationMatrix fixed. Was completely flawed (thanks Sylvain).
• Camera::setOrientation fixed. It used to change the camera position too because of the complex camera frame setup (web page to come). setPosition and setOrientation can now be used in any order. See also setOrientation(theta,phi) in the NEW section.
• Frame::setConstraint() now supports a NULL pointer, which intuitively results in no constraint.
• Camera::FLY mode changed to maintain the horizon.
• Quaternion(from, to) had a problem with angles > pi/2 and null vectors.

• QGLViewer::setDisplayText becomes QGLViewer::setEnableText (idem for QGLViewer::toggleEnableText() and QGLViewer::isTextEnabled()). It controls whether QGLViewer::drawText() actually draws text or not (default is yes). Convenient to remove all the displayed text with a single shortcut ('?' by default).
• Frame::setRotationAxisAngle(), Frame::setOrientationAxisAngle() now take angles expressed in radians instead of degrees.

• Text drawing is done using drawText() directly in draw().
• Key shortcut are no longer defined by static variables. They can be tuned using setShortcutKey() and setShortcutStateKey() See also setMouseStateKey(), setSavePOVShortcutKey(),....
