NAME
       glMultiDrawArrays - render multiple sets of primitives from array data

C SPECIFICATION
       void glMultiDrawArrays(GLenum mode, const GLint * first,
			      const GLsizei * count, GLsizei primcount);

PARAMETERS
       mode
	   Specifies what kind of primitives to render. Symbolic constants
	   GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES,
	   GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP,
	   GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY,
	   GL_TRIANGLES_ADJACENCY and GL_PATCHES are accepted.

       first
	   Points to an array of starting indices in the enabled arrays.

       count
	   Points to an array of the number of indices to be rendered.

       primcount
	   Specifies the size of the first and count

DESCRIPTION
       glMultiDrawArrays specifies multiple sets of geometric primitives with
       very few subroutine calls. Instead of calling a GL procedure to pass
       each individual vertex, normal, texture coordinate, edge flag, or
       color, you can prespecify separate arrays of vertices, normals, and
       colors and use them to construct a sequence of primitives with a single
       call to glMultiDrawArrays.

       glMultiDrawArrays behaves identically to glDrawArrays() except that
       primcount separate ranges of elements are specified instead.

       When glMultiDrawArrays is called, it uses count sequential elements
       from each enabled array to construct a sequence of geometric
       primitives, beginning with element first.  mode specifies what kind of
       primitives are constructed, and how the array elements construct those
       primitives.

       Vertex attributes that are modified by glMultiDrawArrays have an
       unspecified value after glMultiDrawArrays returns. Attributes that
       aren't modified remain well defined.

NOTES
       GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY,
       GL_TRIANGLE_STRIP_ADJACENCY and GL_TRIANGLES_ADJACENCY are available
       only if the GL version is 3.2 or greater.

ERRORS
       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if primcount is negative.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is
       bound to an enabled array and the buffer object's data store is
       currently mapped.
