Original Redmine Issue: 7410
Affected QGIS version: master
Redmine category:symbology
Assignee: Marco Hugentobler

In current master branch if I define the same thickness (Pen width) for line decoration
and symbol line they are rendering in different way both preview and map canvas.

I have noticed this using the TopoViewer plugin.

I attached two images, before and after of merging the branch.

This is still happening as of 83445af, it's pretty annoying.
I shall also notice that there's no way to obtain the old aspect of the arrow in term of angle and length.
Salvatore: do you also have a commit id for what you refer to as "merging the branch" point?

Fix crash when transform errors occur while rendering
452c806 
If a transform exception occurred while rendering a symbol then
the QgsSymbolRenderContext cleanup code was never called,
leading to a double delete and crash.

Fixes qgis#16377, qgis#15345, and numerous other crashes seen "in the wild"

Possibly refs qgis#16385
