    1. What is this and how to install.
    -----------------------------------
    This component lets you to use bitmap fonts with 256 colours.
    Now You can use in Windows Smooth, Coloured etc. Fonts.
    It seems to look quite great. Code is quite dirty but it's no time to clean.
    And it's not fast enough for big texts.

    DEMO: You can watch demo without installing. Just compile project QUICK!	
    INSTALL: Just register UhwReg file


    2. UHW Fonts.
    -----------------------------------------------------------------------------------------
    These are the fonts I used to add to my Dos-programs. The UHW is quite a strange format
    but well... There is no editor for these fonts, I used my primitive DOS-Program which
    converts GIF to UHW files. Look at the file UHWEDIT.ZIP and try make your own fonts.

    3. UHO Palette
    -----------------------------------------------------------------------------------------
    Another component is TUhwPal. It's a small palette component. You can use many different
    palettes to one font, so you will be able to change font colors or shadows.

    4. Methods and properties for TUHWFONT:
    -----------------------------------------------------------------------------------------

    PROPERTIES
    ----------
    property CharSpace :shortint		*** space between each char in pixels
    property PaletteName :string		*** filename of palette for use with font (optional)
    property UhwStrukt:TUhwStrukt		*** font data
    property Palette : TPal768

    You can use different Palettes for any font. So when you need to use the font on different
    backgrounds just change the palette when you need. You have some examples in COL directory
    for use with Arial fonts. Palette format is easy 256*3 bytes (RGB values 0-63).
    It's old Autodesk Animator standard.

    METHODS
    -------
    procedure LoadFromFile(const Text: string);
    > loads *.uhw font from a file

    function  TextWidth(const Text: string): Integer;
    > width of specified text

    function  FontHeight : Integer;
    > height of current font

    function  CharOut  (canvas:TCanvas;X,Y:integer; const Znak: char; ramka:boolean):integer;
    > writes char on canvas at x,y as result gives width of a char
    > see what happens when ramka is true

    procedure TextOut1  (canvas0:TCanvas;X,Y:integer; const Text: string);
    procedure TextOut2  (canvas0:TCanvas;X,Y:integer; const Text: string);
    > writes text on canvas, at x,y coords
    > both procs do the same, they just have different algortyhms.

    procedure TextOutBox(canvas0:TCanvas;X,Y,XX,YY:integer;Text:string;
                         falignx:Talignment;faligny:TalignmentY);
    > writes text in a box (x,y:left-top) (xx,yy-width/height)
      falignx (horizontal allign.) faligny (vertical allign.)

    procedure TextOutBoxSolid(canvas0:TCanvas;X,Y,XX,YY:integer;Text:string;
                         falignx:Talignment;faligny:TalignmentY;backcolor:TColor);
    > the same but fills the box before with backcolor

    procedure TextOutBoxD(canvas0:TCanvas;X,Y,XX,YY:integer;text:obrwsk;
                         falignx:Talignment;faligny:TalignmentY);
    > same as TextOutBox takes text from obrwsk (like-pointer) variable

    function  TextBoxHeight(canvas0:TCanvas;XX:integer;const Text:string):integer;
    > height of box with specified width and text

    function   isCharInSet(ch:char):boolean;
    > is that char definied in the current font?
