have several variants to accommodate different numbers and types of
arguments are collapsed into one or two functions in
<a href="" class="RktModLink" data-pltdoc="x"><span class="RktSym">sgl</span></a>. For example, <a href="" class="RktModLink" data-pltdoc="x"><span class="RktSym">sgl</span></a> provides two
vertex functions: <span class="RktSym">vertex</span> and <span class="RktSym">vertex-v</span>. The
<span class="RktSym">vertex</span> function accepts 2, 3 or 4 numerical arguments, and
the <span class="RktSym">vertex-v</span> function accepts <span class="RktSym">gl-vector</span>s of length
2, 3 or 4. The C language OpenGL interface, in contrast, has 24
vertex functions: <span class="stt">glVertex3i</span>, <span class="stt">glVertex4fv</span>, etc.</p><p>Functions in <a href="" class="RktModLink" data-pltdoc="x"><span class="RktSym">sgl</span></a> take symbols instead of integers for
<span class="stt">GLenum</span> arguments. Each function checks that the given symbol is
an acceptable argument and raises an exception if it is not. Given
the name of a C-language <span class="stt">#define</span> constant, determine the
corresponding symbolic argument by removing the leading <span class="stt">GL_</span>,
converting the letters to lower-case and replacing each <span class="stt">_</span> with
<span class="RktSym">-</span>. For example, <span class="stt">GL_TRIANGLES</span> becomes
<span class="RktVal">'</span><span class="RktVal">triangles</span>, and <span class="stt">GL_TRIANGLE_STRIP</span> becomes
<span class="RktVal">'</span><span class="RktVal">triangle-strip</span>. Additionally, the functions check the
length of any array arguments to ensure that OpenGL does not attempt
to write or read after the array.</p><p>The <a href="" class="RktModLink" data-pltdoc="x"><span class="RktSym">sgl</span></a> module is not as complete as the
