Outline of area not visible
The following statement renders an outline (framing) for an area in Mapforge (see 'stroke-with' parameter):
<area src="file:/patterns/mischwald-einfach.svg" stroke="#69c274" stroke-width="0.05" symbol-width="32"/>
The same statement in VTM leads to nothing or nearly (?) nothing.

Please see https://github.com/mapsforge/vtm/issues/121#issuecomment-238960462 and https://github.com/mapsforge/vtm/issues/121#issuecomment-564531329 and commit https://github.com/mapsforge/vtm/commit/b2a8d3040ad3ad861818467ff17a5f7ffce868b0.
Recommendation: use separate lines (i.e. extra theme rules) for area outlines in OpenGL. Or probably XmlThemeBuilder could make such an addition when parsing an area stroke?
The problem can be solved by splitting the rendering instruction:
Not working:
<area fill="#f1eee9" stroke="#bfbcb7" stroke-width="0.05"/>
Working:
<area fill="#f1eee9"/>
<line stroke="#bfbcb7" stroke-width="0.05"/>
We will change this within the map theme.
Let's keep it open, because:
- Even though it is recommended to split the area + stroke rendering instructions in the themes
- Perhaps VTM theme parser could automatically do the split internally, so all themes can work
