Fix image handling in Fl_Help_View (STR #2163 and STR #2004). 

src/Fl_Help_View.cxx:

This fix is the first step and compatible with FLTK 1.1 (keeping the ABI).
The next step should be to manage the loaded images in an own structure,
because we must know exactly, when to release() the images. The previous
version would release images too many times and could release shared
images that had been loaded by another part of the program (maybe even
another Fl_Help_View widget).

FL/Fl_Help_View.H:

Doxygen comments improved.

*/
/* Implementation note: (A.S. Apr 05, 2009)
Fl_Help_View::get_image() uses a static global flag (initial_load)
to determine, if it is called from the initial loading of a document
(load() or value()), or from resize() or draw().
A better solution would be to manage all loaded images in an own
structure like Fl_Help_Target (Fl_Help_Image ?) to avoid using this
global flag, but this would break the ABI !
This should be fixed in FLTK 1.3 !
If initial_load is true, then Fl_Shared_Image::get() is called to
load the image, and the reference count of the shared image is
increased by one.
If initial_load is false, then Fl_Shared_Image::find() is called to
load the image, and the image is released immediately. This avoids
increasing the reference count when calling get_image() from draw()
or resize().
Calling Fl_Shared_Image::find() instead of Fl_Shared_Image::get() avoids
doing unnecessary i/o for "broken images" within each resize/redraw.
Each image must be released exactly once in the destructor or before
a new document is loaded: see free_data().
