… when using a logarithmic scale), draw_path_collection may get offsets containing NaN's. In that case, using CGContextTranslateCTM once with translation and once with -translation will not restore the original CTM. This bugfix adds a check for NaN/inf.

Should this have been targeted at 1.3.x? |

I'm not convinced it is worth bothering with more 1.3.x fixes now, and this is a fairly obscure bug. |

No this is targeted at master. The bug doesn't manifest itself there, but it's still there. We should fix it now so it won't bite us later. |

See issue #2872. In case of missing values (e.g., zeros when using a logarithmic scale), draw_path_collection may get offsets containing NaN's. In that case, using CGContextTranslateCTM once with translation and once with -translation will not restore the original CTM. This bugfix adds a check for NaN/inf.
