<h4 class="subsection">2.4.4 Lines and Shapes</h4>
<p>Sprites are fun, but sometimes simple, untextured lines and polygons
are desired. That’s where the <code>(chickadee render shapes)</code> module
comes in!

<dt><a name="index-draw_002dline"></a>Scheme Procedure: <strong>draw-line</strong> <em><var>start</var> <var>end</var> [#:thickness 0.5] [#:feather 1.0] [#:cap round] [#:color] [#:shader]</em></dt>
<dd>
<p>Draw a line segment from <var>start</var> to <var>end</var>. The line will be
<var>thickness</var> pixels thick with an antialiased border <var>feather</var>
pixels wide. The line will be colored <var>color</var>. <var>cap</var>
specifies the type of end cap that should be used to terminate the
lines, either <code>none</code>, <code>butt</code>, <code>square</code>, <code>round</code>,
<code>triangle-in</code>, or <code>triangle-out</code>. Advanced users may use
the <var>shader</var> argument to override the built-in line segment
shader.
