+/*! \class fltk::SharedImage
+
+Subclass of Image that can read a file or block of compressed data.
+This provides several useful functions:
+* Images are identified by filename. The static get() function will
+return an existing instance if it was called before with the same filename.
+The release() function will decrement the reference count and delete
+the image if nobody wants it any more.
+* An inline block of data may be provided that is the contents of the file,
+so the file does not have to exist and you can link the image directly
+into your program.
+* You may set a memory usage limit. If Image::mem_used() goes above
+this limit, it will call destroy() on least-recently-used images until
+it goes below this limit.
+* The get() function can determine the type of the file or block of
+data and create the correct subclass.

+ * to derive from this class and then create an instance of that class. With the pointer to that instance
+ * the type of the data is identified.
+ *
+ * possible uses:
+ * - assign key shortcuts to certain widgets
+ * - assign a tooltip to some widgets
+ * - assign a help-index to widgets
+ * - assign a unique identifier to widgets to remote controlling
+ * - assign additional layouting data for new container widgets

+header files and linking with the fltk2.0 library.
+
+Known changes that must be done to fltk1.1 code to make them compile:
+
+Widgets inside groups will need their x,y coordinates fixed as they
+are now relative to the group, not the window.
+
+FL_BOLD, FL_ITALIC - these symbols used to be added to fonts to get
+bold and italic. This no longer works. You should replace them with
+the single symbol for the font (like FL_HELVETICA_BOLD in place of
+FL_HELVETICA+FL_BOLD) or use font->plus(attributes).
+
+Drawing functions are only roughly emulated. You may need to add casts
+to float to get your compiler to locate the correct functions. And if
+you offset by the x,y of the widget you need to remove these offsets.
+
+Some new members of widgets may hide global data. For instance "width"
+and "height" are now members. You can fix this by putting "::" in
+front of the global data names.
+
+If you use the Fl_Browser you are probably going to have trouble. All
+the indexes are offset by 1 from fltk1.1, ie the first item has an
+index of zero, not 1. Adding items with forward slashes in them will
+produce a hierarchy, which is pretty confusing when you don't plan on
+it.
+
+Menu and browser callbacks: the widget passed is the item, not the
+menu or browser. If you use o->parent() to find what window it is in
+you will have to change this, in most cases you can use o->window().

+/** \file
+
+Declarations of FLTK symbols and interfaces that only exist if FLTK is
+compiled on Windows. It is recommended you avoid using this header
+file, and that you segregate code requiring it to it's own source
+file.
+
+This header includes the horrible <windows.h> header file, followed
+by a large list of undef's to get rid of name conflicts. It is recommended
+you use this if you need any windows functions rather than including
+that file directly.
+
+You can probably combine FLTK with other libraries that make their own
+WIN32 window classes.  The easiest way is to call fltk::wait(), it
+will call DispatchMessage() for all messages to the other windows. If
+your other library insists on reading all the events, it will still
+work (as long as it calls DispatchMessage()), but you will
+have to arrange for the function fltk::flush() to be called regularily
+so that widgets are updated. Timeouts, the idle function, and file
+descriptor callbacks will not work in this case.
+
+Many of the functions have the same name and purpose as ones defined
+in x11.h, just with different return types. Due to how Doxygen works,
+the X version of these is described here.

+Declarations of FLTK symbols and interfaces that only exist if FLTK
+is compiled to use X11, as it is by default on Unix. It is recommended
+you avoid using this header file, and that you segregate code requiring
+it to it's own source file.
+
+This header includes the Xlib.h, Xutil.h, Xatom.h, XInput.h, and XI.h
+header files, with sufficent wrappers to avoid conflicts with FLTK.
+In particular a macro is used so that "Window" is replaced by "XWindow"
+in these headers. You should use this rather than including the X
+header files directly.

+README.lib
+----------
+
+This directory is used as a destination for the libraries fltk
+compiles. "make install" will copy them to /usr/local/lib by default.
+
+Fltk will compile a number of libraries, the multiple libraries are
+designed to avoid having programs depend on libraries they are not
+acutally using. For instance if the OpenGL functions were put into the
+main fltk library you would be forced to link OpenGL even if your
+program is not using it. This is a design problem with present-day
+implementations of shared libraries on both Unix and Windows.
+
+The libraries are:
+
+    fltk2 			- the core of fltk2, most programs only need this
+    fltk2_images	- functions that use glut, png, jpg, other image libraries
+    fltk2_gl 		- Fl_Gl_Window and functions that use OpenGL
+    fltk2_glut 		- glut emulation functions
+    fltk2_forms 	- forms emulation functions
+
+Under UNIX you can compile either shared or static libraries. Static
+libraries are the default and have names like libfltk2.a. Shared
+libraries have (on most Unix systems) names like libfltk2.so.2.  To
+enable shared libraries run "./configure --enable-shared".
+
+Under Microsoft Visual C++ a successful build of all projects and
+configurations will contain debug (fltk2d.lib and fltk2dlld.lib) and
+release (fltk2.lib fltk2dll.lib) libraries for you to link to.  Both are
+built using the multi-threaded settings.  The DLL files (fltk2dll.dll
+and fltk2dlld.dll) required for a complete DLL-based binary distribution
+are located in the "visualc" directory. WAS: is this correct? What
+about when you use GCC or BC++?
