+ strings that define a shader. <em class="parameter"><code>shaderType</code></em>
+ indicates the type of shader to be created. Five types of shader
+ are supported. A shader of type
+ <code class="constant">GL_VERTEX_SHADER</code> is a shader that is
+ intended to run on the programmable vertex processor.
+ A shader of type <code class="constant">GL_TESS_CONTROL_SHADER</code> is a shader that
+ is intended to run on the programmable tessellation processor in the control stage.
+ A shader of type <code class="constant">GL_TESS_EVALUATION_SHADER</code> is a shader that
+ is intended to run on the programmable tessellation processor in the evaluation stage.
+ A shader of type
+ <code class="constant">GL_GEOMETRY_SHADER</code> is a shader that is intended to
+ run on the programmable geometry processor. A shader of
+ type <code class="constant">GL_FRAGMENT_SHADER</code> is a shader that is
+ intended to run on the programmable fragment processor.</p><p>When created, a shader object's
