thicker lines for screens with high dpi

[matmay]

Hello,

for me it is quite difficult to see the scope lines, since i have 14" 3200x1800 screen which makes them very thin. I assume they are just one pixel thick.
Everything else is displayed quite nicely.
Maybe I will also find a better color combination for me. For now I have just made the lines brighter.

Thanks,
Matthias

Qt doesn't support the OpenGL function to draw thicker lines - only 1 pixel wide lines are supported. This is a known situation :(
