Steps to repro:

1. Open Unity;
2. Create new project;
3. Add Terrain gameobject (Window -> 3D Object; -> Terrain);
4. Select terrain GameObject in the Hierarchy view;
5. In the Terrain Inspector go to Terrain Settings tab;
6. Observe 'Wind Settings For Grass' section.

Actual result:
'Size' field's naming is uninformative, because it doesn't affect grass size (see attached actual.png screenshot).

Expected result:
Since this field affects grass ripples color, it should be renamed to something more informative.

Notes:
- Reproducible in 5.5.0b5, 5.4.0f3, 5.3.6p2;
- Reproducible on both Windows 10 and OSX 10.11.6.
