Cosimo Lupo dfeacfba36 [varLib.models] minor
We need to use float (0.) rather than int (0) for the normalized axis
origin, otherwise some varLib roundtrip tests may fail.

E.g.

```diff
       <tuple>
-        <coord axis="wght" max="1.0" min="0.0" value="0.61"/>
+        <coord axis="wght" max="1.0" min="0" value="0.61"/>
```
