RVG Resolution DPI doesn't affect pixelation?

[hspinks]

I used RMagick::Draw to build PNGs of line graphs, and they looked great except for the resolution of the lines and text. Looking through the RMagick documentation, I thought RVG would come to the rescue.

Unfortunately, after setting RVG::dpi = 300 and following the tutorial to draw my graph, I still end up with lines and text that appear pixelated. What am I missing?

I've followed the tutorial almost exactly, and you can see some of the code snippet here. Is there a way to improve the pixelation of the lines?

@rmagick @mmaiza any chance you've gotten a chance to look at this issue yet? This is very important to my use of RMagick
