NAME
       glMultiDrawElements - render multiple sets of primitives by specifying indices of array
       data elements

C SPECIFICATION
       void glMultiDrawElements(GLenum mode, const GLsizei * count, GLenum type,
				const GLvoid ** indices, 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.

       count
	   Points to an array of the elements counts.

       type
	   Specifies the type of the values in indices. Must be one of GL_UNSIGNED_BYTE,
	   GL_UNSIGNED_SHORT, or GL_UNSIGNED_INT.

       indices
	   Specifies a pointer to the location where the indices are stored.

       primcount
	   Specifies the size of the count array.

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

       glMultiDrawElements is identical in operation to glDrawElements() except that primcount
       separate lists of elements are specified.

       Vertex attributes that are modified by glMultiDrawElements have an unspecified value after
       glMultiDrawElements returns. Attributes that aren't modified maintain their previous
       values.

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 or the element array and the buffer object's data store is currently mapped.
