[fixed] Materials and quick smoothed preview

[tkbd]

I share a wings file.
This bug may be reproduced if the wings file format also record the flags of display status.

Preferences > Misc > Proxy Mode
EdgeStyle: All Edges
OpenCL proxl level:1

Apply View > Quick smoothed preview
or "show smooth and flat shading" on/off in icon bar.

You can rename the materials so the listing order changes, and with that, the edge display changes in accordance to the new listing order.

This could also be reproduced.(on Wings3D v2.1.4)
In my test case , OpenCL proxl level set 0 then corect display.

If there is a screen cast, I think that everyone is easy to understand.
