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

type

    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
