Dragged resource file over scene should appear at it's drop position, not be centered at cursor

[KoBeWi]

Godot version:
3.1 beta10

Issue description:
Dragging a scene/texture into scene view always shows it at cursor's position. When you drop said resource, it will then align properly to grid or whatever.

E.g. this:

After dropping you get this (snapping to grid enabled):

which is not exactly where you dropped. It's even worse with placing scenes, because if you happen to have a scene with non-centered root, it will be shifted from the cursor by the root offset:

IMO whatever appears when you drag a resource over scene, should appear at it's drop position, not some weird cursor offset. Which means that e.g. texture file dragged into scene should snap to grid from start, not after placing it and moving again.

Snapping to grid can be implemented, but the second part of your issue is a bad idea (and not possible). If your scene's origin is not in the middle of a given sprite, we shouldn't hack it. You probably did this on purpose, you typically have several sprites, etc. If you're dragging a scene, you place its origin, that's normal. Fix the scene's origin if you don't want that.

But the problem with changed origin is this: https://gfycat.com/ChillyFreshIndigowingedparrot

Oh ok, that's buggy then indeed.
