godot/scene/3d/sprite_3d.cpp
MrBlockers 92ebbf2c0a Fix multiple issues with region editor 
Make the filter mode of the texture preview match the node/resource
being edited where applicable, and nearest neighbor with mipmaps as a
fallback.

Make the Edit Region button for Sprite3D only appear when region is
enabled, to match behavior of Sprite2D.

Fix the editor not correctly clearing reference to previously edited
resources, resulting in a visual bug displaying the incorrect texture.
