This commit merge the full development done in greasepencil-object branch and include mainly the following features. - New grease pencil object. - New drawing engine. - New grease pencil modes Draw/Sculpt/Edit and Weight Paint. - New brushes for grease pencil. - New modifiers for grease pencil. - New shaders FX. - New material system (replace old palettes and colors). - Split of annotations (old grease pencil) and new grease pencil object. - UI adapted to blender 2.8. You can get more info here: https://code.blender.org/2017/12/drawing-2d-animation-in-blender-2-8/ https://code.blender.org/2018/07/grease-pencil-status-update/ This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible. Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
