Full refactor of Grease Pencil grid

After testing the old grid locked to view, the artist found that old system was not usable and they requested a grid locked to grease pencil object.

Also fixed some problems with fade object

Now, the color is always white. We still keep internally the color field because maybe we reuse it in the future.
