Merge branch 'blender2.8' into greasepencil-object

Rename function and fix wrong pointer increment

The change done in previous cleanup broken the function.

Cleanup style

Cleanup: Unused variable

Add Force Fill Data parameter

Add a general parameter to force the recalc of the triangulation data because some modifiers could change the geometry and the filling triangles would not be right.

Now, the parameter is visible in UI panel because this option reduces FPS, but maybe in the future we can keep always ON and remove the parameter.

UI: Change text of force recalc

Implement Parent with Empty and Automatic weights

This is an alternative way of define weights.
