BUG pre5, maybe old

[Garst R. Reese]

Set Latex size in a graphic as Custom Width 100 %page
Change to Scale 60%
So far so good, update postscript sees the change.
Save file and exit.
Reload. It is reset to Custom Width 100 %page unless you clear the
numeric field (100).
I think I've seen and reported this a long time ago.
Also, the lyx view says error converting to loadable format file.eps,
but View->Postcript works fine.
