                  Status:         Patch Submitted => In Progress            


Follow-up Comment #10:

I'll fix this *temporarily* with the call to get.  Given that set_linewidth is
called tens of times even for simple plots I think it would be a good idea to
move the overall conversion factor in to a member variable (like
m_devpixratio) that is calculated only once, or when the screen changes.

In that vein, I would also store the single conversion factor so that instead
of two multiplications per call

width = w * points2pixels * m_devpixratio;

there would just be one

width = w * m_linewidth_factor;
