MadButterfly: src/graph_engine

annotate src/graph_engine_skia.cpp @ 1535:9aff42a7e2b9 tip

Fix issue of add/remove a frame at a scene before all key frames of a layer. When you added or removed a frame at a scene before all key frames of a layer, frameline was not updated correctly. It seems nothing happened, but domview is updated. This changeset fix this issue by correcting logic for boundary case.
