Even-odd point in polygon algorithm (see Wikipedia)
Walk around the sides of the polygon and check intersection with each of the sides.
Cast a ray from the point to infinity in any direction and check the number of intersections.
If odd number of intersections, point is inside. Even, point is outside.
Edge cases of point is a vertex or on a side considered.

Again, more complicated. Want to draw the polygon that makes up the 2D-cut. To perform this,
first need to convert plot coordinates into global window coords (pixels). Then tell ImGui to add
a polyline to the draw list, make it red and closed. For this to work, this must be called within the
BeignPlot()/EndPlot() combo for which it was created (why histos own the draw commands).
