Output of wine

In release notes of Wine 1.7.38 support for themed scrollbars is listed.
Release notes of Wine 1.8 again states that this feature is implemented, but
the scrollbar control still ignores color as well as shape provided by the
theme. In fact, no scrollbar related theming is visible at all.

Tested with different themes (Royale, Luna, AeroGlas) and applications, see
attached screen shot of Notepad++ with Royale.msstyles as example.

Wine version: 1.8 (from wine-builds/ubuntu)
Ubuntu 14.04, KDE 4.13.3
