NAME
       glCreateShader - Creates a shader object

C SPECIFICATION
       GLuint glCreateShader(GLenum shaderType);

PARAMETERS
       shaderType
	   Specifies the type of shader to be created. Must be one of GL_VERTEX_SHADER,
	   GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER, GL_GEOMETRY_SHADER, or
	   GL_FRAGMENT_SHADER.

DESCRIPTION
       glCreateShader creates an empty shader object and returns a non-zero value by which it can
       be referenced. A shader object is used to maintain the source code strings that define a
       shader.	shaderType indicates the type of shader to be created. Five types of shader are
       supported. A shader of type GL_VERTEX_SHADER is a shader that is intended to run on the
       programmable vertex processor. A shader of type GL_TESS_CONTROL_SHADER is a shader that is
       intended to run on the programmable tessellation processor in the control stage. A shader
       of type GL_TESS_EVALUATION_SHADER is a shader that is intended to run on the programmable
       tessellation processor in the evaluation stage. A shader of type GL_GEOMETRY_SHADER is a
       shader that is intended to run on the programmable geometry processor. A shader of type
       GL_FRAGMENT_SHADER is a shader that is intended to run on the programmable fragment
       processor.

       When created, a shader object's GL_SHADER_TYPE parameter is set to either
       GL_VERTEX_SHADER, GL_TESS_CONTROL_SHADER, GL_TESS_EVALUATION_SHADER, GL_GEOMETRY_SHADER or
       GL_FRAGMENT_SHADER, depending on the value of shaderType.

NOTES
       Like buffer and texture objects, the name space for shader objects may be shared across a
       set of contexts, as long as the server sides of the contexts share the same address space.
       If the name space is shared across contexts, any attached objects and the data associated
       with those attached objects are shared as well.

       Applications are responsible for providing the synchronization across API calls when
       objects are accessed from different execution threads.

ERRORS
       This function returns 0 if an error occurs creating the shader object.

       GL_INVALID_ENUM is generated if shaderType is not an accepted value.

ASSOCIATED GETS
       glGetShader() with a valid shader object and the parameter to be queried

       glGetShaderInfoLog() with a valid shader object

       glGetShaderSource() with a valid shader object

       glIsShader()
