For the Asset Browser, it needs to be possible to drag assets into various editors, which may not come from the current .blend file. In other words, the dragging needs to work with just the asset metadata, without direct access to the data-block itself. Idea is simple: When dragging an asset, store the source file-path and data-block name and when dropping, append the data-block. It uses existing drop operators, but the function to get the dropped data-block is replaced with one that returns the local data-block, or, in case of an external asset, appends the data-block first. The drop operators need to be adjusted to use this new function that respects assets. With this patch it only works for dragging assets into the 3D view. Note that I expect this to be a short-lived change. A refactor like D4071 is needed to make the drag & drop system more future proof for assets and other use cases.
