This adds the LineArt grease pencil modifier. It takes objects or collections as input and generates various grease pencil lines from these objects with the help of the active scene camera. For example it can generate contour lines, intersection lines and crease lines to name a few. This is really useful as artists can then use 3D meshes to automatically generate grease pencil lines for characters, enviroments or other visualization purposes. These lines can then be baked and edited as regular grease pencil lines. Reviewed By: Sebastian Parborg, Antonio Vazquez, Matias Mendiola Differential Revision: http://developer.blender.org/D8758
