annotate src/shape_path.c @ 489:23c7667b3ec0 Android_Skia

Fix a potential bug when destroy a rdman. When a rdman is dirty, free shapes and coords works specially. Objects are append to a free list. They are not real freed until rdman being clean. redraw_man_destroy() free shapes and coords with free functions of them. If rdman is dirty when destroy it, objects would be leaked. The changeset make rdman clean before free shapes and coords to make objects being freed correctly.
