Fixing perpective flag

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

Change calculation of automatic weights

There were several mistakes and now is using standard routines.

Implement Parent with Empty and Automatic weights

This is an alternative way of define weights.

Enable Fade geometry in Pose mode

Now the grease pencil geometry is fade when the alpha value is enabled.

Rename parent layer when change bone name

Rename bone if Armature modifier

Add weight data when drawing

Keep weight when simplify with RDP

Interpolate weights when subdivide

Manage weights in simplify operator and modifier

More changes to subdivide modifier

Add weights to subdivide points

Improvements in automatic weight calculation
