Without rotation the alignment argument works as expected

plt.PlotText("test", 0, 0, alignment: ScottPlot.TextAlignment.upperCenter);

With rotation it fails, and no alignment properly displays what I want

plt.PlotText("test", 0, 0, alignment: ScottPlot.TextAlignment.upperCenter, rotation: -90);

I want to support both these cases (black point is coordinate, red box is text)
