// (1) let's start with a glyph, this represents one character in a word

type
  TGlyph = record
    character        : Char;         // unsigned char, uchar is something else in delphi
    glyphsSolid[8]   : GlyphTexture; // fast, but not that
    glyphsBlended[8] : GlyphTexture; // slower than solid, but it look's more pretty

//this class has a method, which should be a deconstructor (mog is on his way to understand the principles of oop :P)
  deconstructor  procedure ReleaseTextures();
end;

// (2) okay, we now need the stuff that's even beneath this glyph - we're right at the birth of text in here :P

  GlyphTexture = record
    textureID         : GLuint;      // we need this for caching the letters, if the texture wasn't created before create it, should be very fast because of this one
    width,
    height            : Cardinal;
    charWidth,
    charHeight        : Integer;
    advance           : Integer;     // don't know yet for what this one is
}

{
// after the glyph is done, we now start to build whole words - this one is pretty important, and does most of the work we need
  TGlyphsContainer = record
    glyphs   array of TGlyph;
    FontName array of string;
    refCount          : uChar;       // unsigned char, uchar is something else in delphi
    font              : PTTF_font;
    size,
    lineSkip          : Cardinal;    // vertical distance between multi line text output
    descent           : Integer;
