Option for maximum draw count & rate limiting

[s5bug]

I just wanted to display an image on a PixelFlut server that can't handle pixelpwnr's output of:

1 MiB/s, and can actually only handle about 5 draws per second. I didn't know that pixelpwnr sends images infinitely, which filled up the drawing queue of the PixelFlut server, and now it won't stop drawing the same pixels over and over.

Possibility of an option for maximum speed/maximum draws?

I think a maximum speed/rate limiting may be tricky to implement, and I do not have plans for that. Adding a 'single drawing' option is definitely possible.

I'm currently not actively working on this due to other work, so I'll leave this open for a later time. Feel free to submit a PR for this.

Regarding the maximum speed; maybe something like this can be achieved by limiting the write buffer size, but I'm not sure.

Edit: now that I think of it, a configurable delay between draws should also be easily implementable, which would provide some form of rate limiting.
