How can I save a font (including all its properties like color, angle, etc.) to a 
stream?

Answer:

1   { ... }
2   type
3     FontRec = packed record
4       Color: TColor;
5       LogFont: TLogFont;
6     end;
7   
8   procedure ReadFont(s: TStream; font: TFont);
9   var
10    fRec: FontRec;
11    sz: integer;
12  begin
13    s.read(sz, SizeOf(Integer));
14    if sz = SizeOf(fRec.LogFont) then
15    begin
16      s.read(fRec, SizeOf(fRec));
17      font.Handle := CreateFontIndirect(fRec.LogFont);
18      font.Color := fRec.Color;
19    end;
20  end;
21  
22  procedure WriteFont(s: TStream; font: TFont);
23  var
24    fRec: FontRec;
25    sz: integer;
26  begin
27    sz := SizeOf(fRec.LogFont);
28    if Windows.GetObject(font.Handle, sz, @fRec.LogFont) > 0 then
29    begin
30      s.write(sz, SizeOf(Integer));
31      fRec.Color := font.Color;
32      s.write(fRec, SizeOf(fRec));
33    end
34    else
35    begin
36      sz := 0;
37      s.write(sz, SizeOf(Integer));
38    end;
39  end;
