Figure 1. A single H
This figure represents one H in your H tree and is meant to help you
figure out exactly what coordinates you need to draw lines to and from,
and how thick t to make those lines. The measurements above are
suggestions if you make an H that looks good with other coordinates that
is fine.
The values of currentX, currentY, and currentSize (along with
currentAngle which you will use later) are variables
contained within each H object. You should use these variables within your
draw method.
