[amibroker] Re: Drawing a line from AFL

BTW, this is how eSignal charting "gets away" with using a dog-slow 
scripting language like Javascript and can have reasonable performance 
in real-time markets.   In general, once something is drawn, that's it, 
the user doesn't has to draw it again (in their scripting) because it's 
been written to a bitmap layer in the charting area.  The bitmap layer 
maintains the "memory" of where lines, etc. have been drawn in the past.
