------------------------------------------------------------------------------

     Changes since version 1.16.1 -1.16.3:
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[+]  The new system of fractal landscapes rendering.
     Now for these purposes is used OpenGL(tm), but for start itself, FE
     OpenGL libraries are not required. The lots of rendering functions are
     stored into the separate library, which dynamically loads as required.
     Main possibilities:
       - three independent objects: SKY plane, WATER plane and TERRAIN object;
       - smoothing and blurring of the iteration data;
       - up to five customized light sources;
       - rotating and scaling TERRAIN object;
       - moving and rotating the EYE-point;
       - manipulation with material and/or texture of all objects;
       - the built-in library of carefully fitted textures.
     To use this rendering system you must to download the one file:
         http://skyscraper.fortunecity.com/binary/34/fl_libr.zip
     and unzip it into Fractal Explorer's folder.
[+] Four new coloring methods:
         04. Sine Banding;
         05. Sine Smoothing;
         06. Variation;
         07. Variation II.
    Thanks to Stephen C.Ferguson for the help in their creation.
[+] 12 new filters, which were designed by Stephen C. Ferguson specially
    for FE:
         F-Stalks-1 (I) - (VI);
         F-Stalks-2 (I) - (VI).

[*] the serious error in working with the window of fractal parameters choice
    is corrected.

------------------------------------------------------------------------------
     Version 1.16: changes since version 1.15:
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[+]  "STRANGE" ATTRACTORS: the new version of the rendering system.
     Now it works on two much faster. Besides the set has increased
     possibilities of process control of rendering. The possibility
     has appeared to build and to save the biggest images (up to 1024å1024).

        Attention !
        ~~~~~~~~~~~
        Running of Fractal Explorer now does not need OpenGL support.
        But if in your system the files opengl32.dll and glu32.dll are not
        installed, three-dimensional rendering of "strange" attractors
        will not work !
        You can to receive thess files from:
           http://westwood.fortunecity.com/vuitton/200/opengl.zip
        Unzip the file OpenGL.zip in the Windows/System folder or
        in Fractal Explorer folder.
        Windows 98 users: these libraries are installed in your system !

[+]  new formulae: "Generalized Newton" (I, II and III),
     "4nd Newton var", "Guiatr 2", "Guiatr 3", "Polinom G" and "Polinom M";
[+]  new filters: "Orbit counting" (I, II, III and IV),
     "Gaussian by S.Ferguson", "Atan method" (I and II);
[+]  new 3D-attractors formulae: X+Y+Z+XY+YZ and X+XY+XZ+Y+YX+YZ+Z+ZX+ZY;
[+]  rotation of 3D-attractors on two axes and
     recording of an appropriate AVI-clip;
[+]  rotating of current fractal on 90, 180 and 270 degrees;
[+]  new coloring method of 3D-attractors drawing: "Stilson's with fog";

[!]  now unused filters can be hidden;
[!]  the controls in the dialogue of 3D-attractors are ordered;

[*]  access violation after iterations count changing fixed;
[*]  little bug in filters fixed;
[*]  IFS constructor module: a few bugs are fixed;
[*]  minor bugs are fixed (thanks to Stephen C.Ferguson and Alexey Kravchenko
     for their remarks and advice);

------------------------------------------------------------------------------
     Version 1.15: changes since version 1.14:
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[+]  new version of fractal's landscape rendering, for this we are using the
     RenderLight object by Andy Gibson (http://www.gibsona.demon.co.uk/);
[+]  added some new fractals and filters;

[!]  finished 3D attractor/IFS dialog;
[!]  options dialog separated to "Coordinates", "Color control" and "System"
     dialogs;
