* graphics.in.h, graphics.cc (figure::properties::__mouse_mode__,
figure::properties::__pan_mode__, figure::properties::__rotate_mode__,
figure::properties::__zoom_mode__): New properties.
(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.
