This fix to fl_height(int,int) solves the "digital drit"
problem in Fl_Text_Editor, where doing insert/delete
operations was leaving a trail of dead pixels.
Also fixes problem with font display problem in fluid's
code editor. See the STR for screenshots of the problem.
NOTE: THIS IS A WORKAROUND FOR A DEEPER PROBLEM.
Somewhere during the port of UTF8, the actual pixel size
of the displayed font is a little off, causing FLTK to
miscalculate line height, causing 'digital drit'.
It used to be that when you specified a font size,
the font's actual displayed pixel size matched the
font size value.
This fix makes the fl_height(int,int) function more robust,
actually inquiring the font system for its font size, instead
of assuming the font size is the same as the 'size' argument.
Since Fl_Text_Editor makes use of this function, it helps
that widget calculate font sizes correctly.
The real fix will be restoring FLTK's old behavior where the
font size specified is the actual pixel size of the displayed font.
Then this function can be reverted to just returning the 'size' argument.

- set_menu_window() to mark a window as a menu window
- set_tooltip_window() to mark a window as a tooltip window
and the corresponding get methods:
- menu_window()
- tooltip_window().
This is a first step for providing more information for correct parenting
and properties to support modern (X) window managers (STR #2230).

ToDo: Another point is to be able to handle menu windows and popup windows
that are opened while a menu is active properly (will follow later).

before deleting them with delete or Fl_Widget::delete_widget(). This is not
necessary any more, but it was necessary in FLTK 1.1.

Also, unittest added (scrollbar size) to test these changes.
Thanks to Albrecht for testing/peer review.

+ Replaced uninitialized C parameters archaisms, by on the fly C++ local var. decl.
Not only it will be more optimized by modern c++ compilers,
code is easier to read, maintain and debug and is shorter.
Most local variables are now explicitly intialized when declared.
+ Replaced some non const vars by const equivalents when required.

+ Made char * text() const., this method should be further checked for UTF8 compat.
+ Added a fixme comment to remember we must check for the potential incorrect
assumption that that a buffer size equals the string length + 1.
+ Correct a protected attrib. typo as we don't need to care about ABI compat. for now.
