Related tdf#148569: do not apply macOS fix to non-macOS platforms
Setting the stroke width and cap has a noticeable performance penalty
when running on GTK3. Since tdf#148569 only appears to occur on macOS
Retina displays, revert commit a4488013ee6c87a97501b620dbbf56622fb70246
for non-macOS platforms.
