 --
 --                            8/93:    updated file to work with the ß2 "GXified" interface files

 --        File:        Getting Started GX - shapes.c
 --
 --        Comments:    This code demonstrates creates, manipulates, and draws all of the QuickDraw
 --                    GX shapes used in this app. This is the same code which was used during the
 --                    "Getting Started With QuickDraw GX" WWDC '93 session.
 --
 --                    This application will also support multiple windows. We present two menus
 --                    to the user to draw into the contents of the window. The "Graphics" menu
 --                    allows the user to create a platinum rectangle and rotate a text shape ("QD GX")
 --                    from the lower left corner 45 degrees. The font used within the text shape
 --                    is the "Skia" font. This font contains font variation information. This information
 --                    allows us to change the various axes within the font to receive different
 --                    effects. In our case, we retrieve information regarding the 'wght' axis of the
 --                    font and set it to the maximum width allowed. By setting the 'wght' axis to the
 --                    maximum, we receive nice fat letters. Each letter of the text shape is colored
 --                    in a different CMYK color. We will also outline each character in black. Finally,
 --                    we add a star pattern to the "X".
 --
 --                    As each letter is drawn, you can see the "gxAndMode" transfer mode applied as
 --                    the characters overlap.
 --
 --                    The second menu "Typography", creates and manipulates a layout shape. The first
 --                    menu item will create the layout shape. Once you have created the layout shape,
 --                    you will recieve the "as" ligature in "Nasty", swashes for the "C", "N", and "D",
 --                    the final form of "e" in "Dude", and the automatic kerning of "WAVE".
 --
 --                    For all of the layout effects to work, you need the following fonts installed into
 --                    your system:
 --
 --                    • Hoefler (this font will be automatically installed, if you use the Installer Script)
 --                    • Skia
 --                    • HonMincho
 --                    • Times
 --
 --                    All of the fonts listed above (except Hoefler), can be found in the "Testing Fonts"
 --                    Folder contained within the "• Open Me First! •" folder. If these fonts are _not_
 --                    installed, you will recieve font substitution, and you will receive interesting
 --                    characters when the Kanji text is drawn.
 --
 --                    The next item allows you to add two-byte Kanji text to the layout shape. The last
 --                    item allows you to perspect the layout shape.

 --                    The file titled: "Getting Started GX - main.c" contains the code required
 --                    to intialize and tear down the QuickDraw GX world, and the event loop.
 --
 --                    The file titled: "Getting Started GX - printing.c" contains the code required
 --                    to print the contents of the window.

 --
 --        QuickDraw GX
 --        Libraries
 --        Used:        This application uses the following QuickDraw GX library code files:
 --                    "ColorLibrary.c", "FontLibrary.c", "GraphicsDebugLibrary.c", "LayoutLibrary.c",
 --                    "ShapeLibrary.c", "TransferModeLibrary.c", and "TransformLibrary.c".
 --
 --
 --        Notes:        1) Print this file in landscape for the best results
 --                    2) If you are using THINK C v6.x, I have added THINK markers to navigate the code.
 --                    3) This code was adapted from the "Banana Jr." QuickDraw GX sample.

    //    multiple runs of text. Each run can use: a different font, text size, run features,
    //    run controls.
    //

    //    Hoefler Italic font. We acheive this goal by setting the runFeatures featureType
