VSE: Add precise drag and drop and strip previews

Browse Source 
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.
