Hello,

First post for me and I'm still learning Cocos2d. So bear with me.

I played a bit with test_tmx.py. I added this code

    def on_key_press(key, modifier):
        if key == pyglet.window.key.Z:
            if scroller.scale == .75:
                scroller.do(actions.ScaleTo(1, 2))
            else:
                scroller.do(actions.ScaleTo(.75, 2))
        elif key == pyglet.window.key.D:
            test_layer.set_debug(True)
        elif key == pyglet.window.key.F:
            test_layer.set_cell_color(0, 0, (255, 0, 0) )

I notice that this colorize indeed first cell (bottom left), but the black 
region is still black. This seems to make sense as the colors are 
multiplied, if I understood correctly. What should I change if I would like 
to have a reddish hue on this cell. The idea is to highlight some cells 
with a color, so the player can know where he can move for instance.

Also in this demo, when I use the scaling to 0.75, we see black lines from 
the grid while the car is moving. Is there something I could do to minimize 
this problem?

And last question, if my intention was to draw a grid, how should I 
proceed? Of course I could add another layer with its own grid, but I feel 
like it's unnecessary duplication. The vertex are already there. Can we 
still show the quads border while using textures?

Thanks for your help,
Dan.
