        !            12:   Drawing the Mandelbrot set and the corresponding julia
        !            13:   set
        !            14:   Zooming into any of the set
        !            15:   MDI fractal drawing windows
        !            16:   Floating Point Math/Fix Point Math
        !            17:   Shifting color table entries
        !            18:   Changing palette entries and animating palatte aka color
        !            19:   cycling
        !            20:   Loading/Saving bitmap created with special effect
        !            21:   Changing bitmap color with flood fill
        !            22:   Boundary tracing and creating a clip region out of it for
        !            23:   creating special effect
        !            24:   Enumerate printers for printing
        !            25: 
        !            26: 
        !            27: Drawing the Mandelbrot Set and the Corresponding Julia Set
        !            28: 
        !            29: 1.To draw the Mandelbrot set, choose the Mandelbrot Set
        !            30:   menu item from the Create menu to create a MDI child
        !            31:   window to draw the set in if one has not already been
        !            32:   created.
        !            33: 
        !            34: 2.Then, choose either "use Fix Point math" or "use Floating
        !            35:   Point math" from the Draw menu to decide if floating
        !            36:   point or fixed point math is desired for calculation.
        !            37:   Fix Point is faster, however you lose resolution sooner
        !            38:   as you zoom in.
        !            39: 
        !            40: 3.Also, choose the number of iterations from the Iteration
        !            41:   menu item and choose Step from the Draw menu.  The higher
        !            42:   the number of iterations, the more detail is the picture
        !            43:   but the slower to generate the picture.  The step
        !            44:   determines whether every scan line is drawn.  The more
        !            45:   scan lines it has, the better the picture but the slower
        !            46:   to generate the picture.
        !            47: 
        !            48: 4.To start drawing, choose Draw Set from the Draw menu.
        !            49: 
        !            50: 5.To draw the Julia set, use the right mouse button to
        !            51:   select a point in the Mandelbrot set (the drawing surface
        !            52:   of the Mandlebrot window). A new Julia MDI window will be
        !            53:   created.  Then choose Draw Set from the Draw menu to
        !            54:   start drawing.
        !            55: 
        !            56: 6.The point selected with the right mouse button determines
        !            57:   the complex constant to use for the Julia Set.
        !            58: 
        !            59: Zooming Into Any of the Set
        !            60: 
        !            61: 1.To zoom in, click, drag and release with the left mouse
        !            62:   button to describe the zoom in region.
        !            63: 
        !            64:   A new MDI child of the same type as the parent
        !            65:   (Mandelbrot window or Julia window) will be created.
        !            66: 
        !            67: 2.Choose Draw Set from the Draw menu to start drawing.
        !            68: 
        !            69: MDI Fractal Drawing Windows
        !            70: 
        !            71:   Choose either Mandelbrot Set or Julia Set from the Create
        !            72:   menu for creating a new MDI window for drawing.
        !            73: 
        !            74:   Or, use the left mouse button to describe a zoom in
        !            75:   region in either a mandelbrot or Julia MDI window for
        !            76:   creating a new MDI window for drawing.
        !            77: 
        !            78:   Or, click on the Mandelbrot window with the right mouse
        !            79:   button for creating a Julia MDI window corresponding to
        !            80:   the mouse click position in the Mandelbrot window.
        !            81: 
        !            82: Floating Point Math/Fix Point Math
        !            83: 
        !            84:   Choose the appropriate menu item ("Floating Point math"
        !            85:   or "Fix Point math") from the Draw menu.  The Fix Point
        !            86:   math uses 20.11 fixed point integer arithmetic for
        !            87:   calculation.

        !            92:   color table entry.  The picture of the active MDI window
        !            93:   will be updated.
        !            94: 
        !            95: Changing Palette Entries and Animating Palatte (aka Color

        !            99:   color cycling the picture.
        !           100: 
        !           101:   The menu item will be grayed if the display device does
        !           102:   not support palette management.  Currently, only the MIPs
        !           103:   display driver supports that.
        !           104: 
        !           105: Loading/Saving Bitmaps Created With Special Effect
        !           106: 
        !           107:   Choose Load Bitmap from the Bitmap menu to load a bitmap
        !           108:   into the active child window.  Or, choose Save Bitmap As
        !           109:   to save the picture in the active MDI child window.
        !           110: 
        !           111: Changing Bitmap Color With Floodfill
        !           112: 
        !           113:   Choose Custom from the Color menu to select a color.
        !           114:   Then the cursor will be changed to a paint can over the
        !           115:   active child window.  Click with the left mouse button on
        !           116:   the picture, the old color under the cursor will be
        !           117:   changed to the new color.

        !           121: 
        !           122:   From any active Mandelbrot window, choose Set Mandelbrot
        !           123:   Clip region from the Region menu.  The boundary of the
        !           124:   escape region will be traced.  The region will then be
        !           125:   selected as a clip region.
        !           126:    
        !           127:   Thus, if you load a bitmap for display, the bitmap will
        !           128:   only show through the clip region.  The new picture can
        !           129:   then be saved.
        !           130: 
        !           131:   To remove the clip region, choose Remove Clip Region from
        !           132:   the Region menu.
        !           133:

        !           135:   small island of only several pixels and stop.  If that
        !           136:   happens, you might change the size of the window or
        !           137:   create another zoom window and trace again.

        !           141:   On start up, the Mandelbrot Dream will enumerate the
        !           142:   printers and insert the printers into the Print menu.
        !           143:   Then selecting the printer on the Print menu will print
        !           144:   the picture in the active MDI window.
