This method can be called after all menu modifications to make sure
the menu() array is relocated (copied from the internal working area)
to a private place owned by the Fl_Menu_ instance.
menu_end() is now called in Fl_Menu_Button::popup() to make sure
the menu array is in private storage.
This fixes STR 3523 w/o user code changes. Calling menu_end() is
in most cases optional.
Todo: call menu_end() where useful (or necessary), e.g. in
Fl_Choice, Fl_Menu_Bar, etc. ?
Rename member function Fl_Surface_Device::end_current_() to end_current(),
set it protected, and make it called by the destructor of all classes
derived from Fl_Surface_Device that re-implement end_current().
This way, end_current() runs equally if Fl_Surface_Device()::pop_current()
is called before or after the drawing surface is deleted.
Particularly to Doxygen docs and NEdit which appears to have moved
to sourceforge (according to Wikipedia), see

Note: nedit.org exists but shows some non-English text.
In the context of HighDPI screens, the API of function fl_read_image()
is inadequate because a rectangle of size WxH drawing units
of a window may contain many more than W*H pixels.
Function fl_capture_window_part() returns an Fl_RGB_Image
object whose drawing size matches the size of the rectangle
and whose data size matches the, possibly larger, size in pixels
of the corresponding area of the mapped window.
o Added mention of drag+drop / FL_TREE_SELECT_SINGLE_DRAGGABLE
to list of features on main Fl_Tree doxygen page.
o Whitespace mods to FL_TREE_SELECT_* to fix doxygen 1.8.5
whitespace sensitivity that was causing single sentence
to break into two when spanning multiple "///>" comments
for last item in an enum (doesn't end in ",")
This commit adds a cairo_surface flush after calling the draw callback.
This fixes the test/cairo_test demo program under Windows.
At least under Windows the Cairo callback used in Fl_Cairo_Window
didn't draw anything with current Windows 10, MinGW (32-bit) and
Cairo 1.15.12 for Windows. It worked well under Linux though. Anyway,
the flush should do no harm.
