FLTK associates to each surface a <tt>struct fl_wld_buffer</tt> (see \ref fl_wld_buffer) containing
a pointer to the byte array of the Cairo image surface (member \c draw_buffer), a pointer to the
Wayland buffer (member \c wl_buffer), and other information. A pointer to this
a pointer to the byte array of the Cairo image surface (member \c draw_buffer), information about the
Wayland buffer (members \c wl_buffer and \c data), the common size of the Cairo surface's and
Wayland buffer's byte arrays (member \c data_size), and other information. A pointer to this
<tt>struct fl_wld_buffer</tt> is memorized as member \c buffer of the Fl_Window's \ref wld_window.
All drawing operations to the Fl_Window then modify the content of the Cairo image surface.

no effect at present, without this preventing input methods that have been tested with FLTK to work
satisfactorily.
For text input methods to work as expected, it's necessary to inform them of the current location of the
insertion point in the active surface because this information allows text input methods to map their
auxiliary windows next to this point, where they are expected to appear.
The flow of information on this topic is as follows:

- The two FLTK widgets supporting text input, Fl_Input_ and Fl_Text_Display, transmit to FLTK the window
coordinates of the bottom of the current insertion point and the line height each time they change
calling function \c fl_set_spot().
