setOutlineThickness negative values

[model76]

Hi Laurent,

In SFML 1.x you could give negative values for outline thickness. This was really practical for outlining without changing the size of the shape. This is not possible with SFML 2, where negative values for setOutlineThickness aren't allowed.

I hereby request that the feature be added to SFML 2.

Done

It seems that there were no good reason to disallow it.

Thanks for your feedback.
