(figure::properties::set___mouse_mode__): New function. (axes::properties::pan, axes::properties::rotate3d, axes::properties::zoom): New functions. Handle zoom, and pan modes. (axes::properties::clear_zoom_stack): New arg, do_unzoom. Conditionally call unzoom. (axes::properties::unzoom): Also restore view property. (axes::properties::rotate_view): Conditionall save state to zoom stack. (axes::properties::push_zoom_stack): New function. (axes::properties::pan, axes::properties::rotate3d): Delete properties. (axes::properties::update_xlim, axes::properties::update_ylim, axes::properties::update_zlim): Don't clear zoom stack. Delete do_clr_zoom argument. (axes::properties::set_pan, axes::properties::set_rotate3d): Delete. (F__zoom__): New function. * Canvas.h, Canvas.cc (Canvas::toggleAxes, Canvas::toggleGrid): New pure virtual functions. (Canvas::setCursor, Canvas::canvasToggleAxes, Canvas::canvasToggleGrid, Canvas::canvasMouseDoubleClickEvent, Canvas::canvasWheelEvent): New functions. (zoom_enabled, pan_enabled, pan_mode, rotate_enabled, rotate_mode): New static functions. (Canvas::canvasMouseMoveEvent): Call axes::properties::rotate3d to do rotation. Handle panning. (Canvas::canvasMousePressEvent): Also handle "unzoom" action when in pan and rotate modes. (Canvas::canvasMouseReleaseEvent): Zoom by factor if mouse has not moved from mouse press event. * Figure.h, Figure.cc (MouseMode): New enum value, TextMode. (Figure::m_mouseMode, Figure::m_lastMouseMode): Delete member variables. (Figure::mouseMode, Figure::setMouseMode): Get info from and save info to figure properties. (Figure::updateFigureToolBarAndMenuBar, Figure::toggleAxes, Figure::toggleGrid): New functions. (Figure::m_mouseModeGroup): New member variable. (Figure::createFigureToolBarAndMenuBar): Add actions for toggling Axes and Grid. Maintain pointer to MouseModeActionGroup. (mouse_mode_to_string, mouse_mode_from_string): New functions. * GLCanvas.h, GLCanvas.cc (GLCanvas::toggleAxes, GLCanvas::ToggleGrid, GLCanvas::mouseDoubleClickEvent, GLCanvas::wheelEvent): New functions. * MouseModeActionGroup.h, MouseModeActionGroup.cc (MouseModeActionGroup::mouseMode): Delete. (MouseModeActionGroup::setMode): New function. (MouseModeActionGroup::MouseModeActionGroup): Also include action to insert text in the list. * figure.m: Set default pan, rotate, and zoom mode properties for the figure object. * pan.m, rotate3d.m, zoom.m: Improve compatibility with Matlab. Set mode properties for figure. * __init_fltk__.cc: Cope with changes to graphics properties.
