I see that the change was made in a hurry... I attached a glyph that when 
converted to quadratic splines, throws an IError message, but the 
resulting outline is OK.

Surprisingly, the new algorithm seems to produce /fewer/ points, but when 
I do element->round->round_to_int, it makes the point number much greater, 
because all the interpolated points are rounded too, and so they are no 
longer in the middle of their control points, and so they becomes 
non-interpolated...

FF also segfaults when openning any .pfb font or when, having multiple 
fonts opened, one is closed. But I think You noticed this before.
