        Creates and new AWTGVTGlyphVector from the specified GlyphVector and AWTGVTFont objects.
        Parameters:
        glyphVector - The glyph vector that this one will be based upon.
        font - The font that is creating this glyph vector.
        scaleFactor - The scale factor to apply to the glyph vector. IMPORTANT: This is only required because the GlyphVector class doesn't handle font sizes less than 1 correctly. By using the scale factor we can use a GlyphVector created by a larger font and then scale it down to the correct size.
        ci - The character string that this glyph vector represents.
