This patch adds the drag and drop strip previews in the VSE. It also adds two new functions to the drag and drop API. 1. "draw_in_view" for callbacks that wants to draw elements in local viewport coordinates 2. "on_drag_start" that can be used for prefetching data only once at the start of the drag.
