Changes: Simple cleaning for MPositionIndicatorView::drawContents()

RevBy: Armin Berres

Details:
This patch use local variables to avoids calls to model() and style().

The method model() is not inline, calling it 3 times in a row was
unecessary.

Each call to style()-> was invoking 2 non-inline functions:
-style() itself
-currentStyle() for operator->()
