This is as rare as it sounds. If you attempted to segment a path like `M0,0zM1,1z` with the `npoint()` code it would fail. There's a rare fallback when total length equals zero (and there exists segments). But, this was not properly fixed for use with `numpy`.

What's Changed
* `npoint()` zero length fallback by tatarize in https://github.com/meerk40t/svgelements/pull/191

While not specifically referenced in CSS the actual testing quickly showed that short hand font names are overwhelmingly tagged with '' quote text. This didn't seem to be indicated in my initial reading of the spec, but in practice is quite common.

Typo in the default family for fonts without a declared family.

What's Changed
All breaking changes (hence 1.7.0) are confined to the text object parsing and interactions with text objects.

* Deprecated Font-Face Text Attribute.
* Correctly implement font-style
* Correctly implement font-variant
* Correct implement font-stretch.
* Fix ReDoS issue with font-shorthand parsing.
* Correct rounding error converting between `pt` and `px`
* Text.font_weight may now return a regular str element.
* Text.weight gives parsed value of font weight.
* Text.font_list will provide the list of CSS Font Families in order.
* Text.font_family will provide the font_family (**This is a breaking change.**)
