virtual void Draw ( UObject* Object, int32 X, int32 Y, uint32 Width, uint32 Height, FRenderTarget, FCanvas Canvas, bool bAdditionalViewFamily )	Begin UThumbnailRenderer Object.	ThumbnailRendering/SlateBrushThumbnailRenderer.h
virtual EThumbnailRenderFrequency GetThumbnailRenderFrequency ( UObject* Object ) const	Override this method to control the render frequency for thumbnails in your editor Generally speaking you should use Realtime if you want an animated thumbnail, but if not it is expensive to use (per-frame draws) If not using realtime, the next best default is OnAssetSave, which updates the thumbnail only save.
