Some remarks: it would be nice to use "faded" dots, but I had no time to put a blurring algo in this. Also, the drawing operations would benefit from
using a bit more high-quality drawing engine than GDI, for instance my new pyro lib
Right now you can see the stepping on all the lines and blips.
Current demo only uses GDI, with pf8bit bitmaps and some low-level bitmap fumbling. You could optimize it surely with MMX and such.

I updated a few things:
- More comments: this is also a nice example on how to draw "flicker-free" using a paintbox
- Removed timer in favour of direct invalidating
- List frames per sec (I get 64 fps on my system when including a sleep(1)in the loop to avoid stressing the processor)
- Some minor tweaks and bugfixes.
