[Art Pencil]
I haven't added drawing, because it uses lots of panels and start s lagging only because of function count overload (at my pc above 2000 'ticks'(panels) ).
Of course, I can upload it and post link too, if you want.

I love A7titude, it's made very proffesional, but I think adding some mipmapping will be nice. Btw, it's code is nearly unreadable. (Need to do lot's of find\replace to understand something.)
