Context is needed to import and instantiate assets correctly. Previously
the context was stored as "evil" pointer in the drag data. Since
77794b1a7b, context is passed to the dragging callbacks doing the asset
import, so the context doesn't need to be stored that way anymore and
can simply be passed to the import function.
