Painting weights in Grease Pencil with the auto-normalize option enabled, gave unpredictable results when vertex groups with a weight of zero were involved. This patch resolves the issue. Vertex weights of zero are excluded from auto-normalization. Which is a better fit for the Grease Pencil workflow, where weights are mostly painted from scratch since the 'parent to armature with automatic weights' operator doesn't give good results.
