3DM file thumbnails in the File View dialogue window

[paulharrisandme]

When clicking on Import 3DM in the Blender interface it opens the File View dialogue - but when navigating to a folder with 3DM files inside there are no thumbnails to help identify which file to select - even though thumbnails are visible in a Windows Explorer window of the same folder.

Another options would be to enable dragging-and-dropping of 3DM files from the Windows Explorer directly into Blender?

I'll have to see if Blender supports adding handlers for files to have thumbnails show up in the file dialog.

Based on first investigation there is no way currently to register file handlers with the file browser in Blender to be able to collect the thumbnail from the 3dm.

I'll leave this open as a feature request that we can revisit when there are facilities in Blender to register custom file type handlers.

Perhaps the assets API in Blender could in the future provide the necessary parts, but it'd be better if this were tied into custom filetype support.
