\brief The FrameNavigator is a simple toolbar widget showing a numerical
representation of an integer timeline.
\details A FrameNavigator is a TFrameHandle viewer composed of a line edit
widget showing the current frame number, and a pair of directional
arrow buttons that move to adjacent frames.
\remark The text field actually visualizes the internal integer \p m_frame \a +1
(e.g. when \p m_frame is 0 then 1 is visualized).
