I'd like to move this forward.

Now, when any text is rendered on the given path, there are some boundaries on that path where characters can be placed. It works even for compound paths, see e.g. this: http://drifted.in/other/fillrule-evenodd.svg

The text outside this boundary is clipped. My idea is to, optionally, enable rendering of these clipped parts on the opposite side of the path, starting at that opposite boundary. In the example above the (laz)'y dog' phrase would continue and cover the '>The quick brown' phrase. 

While this behaviour looks weird, it can be very handy in some cases.

See e.g. this: http://drifted.in/other/text_path.svg

This quite natural usage has to be encoded into over-complicated code and finally rotated.

Things could be much easier using that new option - I commented it in that svg file above.

I have no objections to call it 'text-overflow' as suggested above. A default value would be 'clip' and a new one either 'overflow' or 'visible'.

Thanks, Jan
