Bugs fixed and features added.

Hi Roman, I thing than " Added 'null' key " is not a good idea because generator software cannot guest what it should generate for 'null'. This introduces human action on font files whereas it is fully automated at the moment.

May I suggest an hard coded drawLine() instructions in the printing/rendering routine when the character is missing in the font? This would preserve the automated ft-generator (I'm planning to produce other fonts when fonts will be encoded inside binary font files). This would also avoids human update in the Arial_14.py file (and the other).

We may change empty keys with something. Shore You may suggest. Thanks.

Why not drawing an white box or white rectangle? (with font height and font height). In normal operation, user would not print missing characters... and drawing a box will indicates an issue with a missing character in the font. Such approach would also make sense for the Windings (Glyphs) fonts where character availability is very unpredictable.

I would suggest the printChar() to take it in charge himself. So it would work properly with all fonts.

Here a suggestion with meta code.

    def printChar(self, char, x, y, cont=False, scale=None):
        if not scale:
            scale = self._fontscale
        font = self._font
        if self.portrait != ILI._portrait:
            self.portrait = ILI._portrait
        self._fontscale = scale = 5 if scale > 5 else scale
        index = ord(char)
        height = font['height']
        try:
            chrwidth = len(font[index]) * scale
            data = font[index]
        except KeyError:
            data = None 
            chrwidth =  font['width'] * scale
        X = self.TFTHEIGHT - y - (height * scale) + scale
        Y = x
        self._char_orientation()
        # Garbage collection
        self._gcCollect()
        if data == None:
             drawing the rectangle here
        else:
            self._fill_bicolor(data, X, Y, chrwidth, height, scale=scale)
        if not cont:
            self._graph_orientation()

It's true. I will fix that.
