SGPLOT line thickness misbehaving with higher resolution svg files.

hi

The following 2 pieces of code produce very different graphs even though the line thickness is 1.9px in the first and 2.0px in the second.  It doesn't matter whether I use pt or px as the units (it just breaks at a different point). 

If i create a png image instead of svg, it behaves exactly as expected.  If I leave out the image_dpi option it behaves as expected.  Using a lower dpi reduces the problem while higher dpi makes the problem even worse.

I require an svg file with at least 600dpi and I’d like to get an image with a line thickness somewhere between ultra-fine and pre-school crayola.  

CODE 1:

ods html close;
ods html5 options(svg_mode="embed") image_dpi=600;
ods graphics /imagefmt=svg;
proc sgplot data=_plot noautolegend;
step x=time y=Survival / group=Stratum lineattrs=(thickness=1.9px);
scatter x=time y=Censored / group=Stratum markerattrs=(symbol=plus size=8);
run;
ods html5 close;
ods html;

CODE2:

ods html close;
ods html5 options(svg_mode="embed") image_dpi=600;
ods graphics /imagefmt=svg;
proc sgplot data=_plot noautolegend;
step x=time y=Survival / group=Stratum lineattrs=(thickness=2px);
scatter x=time y=Censored / group=Stratum markerattrs=(symbol=plus size=8);
run;
ods html5 close;
ods html;
