Don't use rounded corners for PopupMenus in the editor theme
Don't use rounded corners for PopupMenus in the editor theme

PopupMenus use separate windows by default in the editor, and windows
no longer support per-pixel transparency for now in 4.0.
Even if per-pixel transparency was reimplemented, we can't assume
that it'll always work in practice (e.g. when compositing is disabled).
