NaN values in vectoriser

[jaw]

This here crashes when d[0] or d[1] is NaN which apparently can happen with some characters in some fonts. Not sure why there would be such values.

This is where the segfault happens (inside the glu library): https://github.com/ulrichard/ftgl/blob/16f7667cbd4b1e988ae24128c5dea54479926f85/src/FTVectoriser.cpp#L326

I have implemented a crude fix here: https://github.com/vovoid/ftgl/commit/d7b50a5a240f89a1e916274231cca0c8150bdf08

Can you give an example which characters from which fonts, and which FTGL drawing mode and settings you used to cause the problem, so I can reproduce it?

Note that my fork (https://github.com/frankheckenbach/ftgl) seems to be the "official" one now (e.g. used in Debian). ulrichard didn't want to keep maintaining this one anymore.

Sure thing! You'll have it on tuesday next week.
