This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes. Also, a huge code cleanup has been done at all levels. Thanks to @fclem for his work and yo @pepeland and @mendio for the testing and help in the development.
