DESCRIPTION
    Lens magnifies the area surrounding the current position of the mouse cursor.
    The size of the area is determined by the size of the lens window.

    The zoom factor can be changed using the "File/Zoom in" and File/Zoom out"
    menu items or using the "+" and "-" keys. It is limited by the size of the
    lens window. F.e. the default size of lens window allows a 32x magnification.
    If you double the size of the lens window, you'll double the maximum magnification
    factor to 64x.

    When the lens window is active the cursor keys can be used to move the
    mouse cursor. This makes it easier to move the cursor one pixel at a time.
    The following keys are recognized:

        Up          Move the mouse cursor 1 pixel up.
        Down        Move the mouse cursor 1 pixel down.
        Left        Move the mouse cursor 1 pixel left.
        Right       Move the mouse cursor 1 pixel right.

        Shift-Up    Move the mouse cursor to the top of the screen.
        Shift-Down  Move the mouse cursor to the bottom of the screen.
        Shift-Left  Move the mouse cursor to the left of the screen.
        Shift-Right Move the mouse cursor to the right of the screen.

        Ctrl-Up     Move the mouse cursor up by the size of the lens.
        Ctrl-Down   Move the mouse cursor down by the size of the lens.
        Ctrl-Left   Move the mouse cursor left by the size of the lens.
        Ctrl-Right  Move the mouse cursor right by the size of the lens.

        Home        Move the mouse cursor to the top-left corner of the screen.
        End         Move the mouse cursor to the bottom-left corner of the screen.

        Esc         Exit the lens application.

    A hot key is available to be able to activate the lens window. Currently this
    hot key is fixed at Ctrl-Shift-L.

    In the status bar of the lens window the current X and Y coordinate of the mouse
    cursor is shown, the RGB value (in hexadecimal) of the color under the mouse
    cursor and the current magnification factor.

    The refresh rate is currently fixed at 20 frames per second which may put a
    strain on systems with older CPU's and/or graphics cards.

HISTORY

1.01    Released on 2001/10/03
        - Improv.: Extended the use of the cursor keys.
        - Improv.: Added a hotkey to activate the lens window without moving the
                   mouse cursor.
        - Improv.: Added a small description of the current feature set to this
                   file.
        - Bug fix: The zoom factor was reset after minimizing the lens window.
        - Bug fix: The magnifaction code kept running when the lens window was
                   minimized resulting in a few wasted CPU cycles.
