prose <<~TEXT
The cap style defines how the edge of a line or curve will be drawn.
There are three types: <code>:butt</code> (the default),
<code>:round</code> and <code>:projecting_square</code>.
The difference is better seen with thicker lines. With <code>:butt</code>
lines are drawn starting and ending at the exact points provided. With
both <code>:round</code> and <code>:projecting_square</code> the line is
projected beyond the start and end points.
Just like <code>line_width=</code> the <code>cap_style=</code> method
needs an explicit receiver to work.
