glGenLists - generate	a contiguous set of empty display
lists

glGenLists
	glGenLists(range) -> listBase

GLuint glGenLists( GLsizei range )

range	 Specifies the number of contiguous empty display
       lists to be generated.

glGenLists has one argument, range.  It returns an integer n
such that range contiguous empty display lists, named	n,
n+1, ..., n+range -1,	are created.  If range is 0, if	there
is no	group of range contiguous names	available, or if any
error	is generated, no display lists are generated, and 0 is
returned.

GL_INVALID_VALUE is generated	if range is negative.

GL_INVALID_OPERATION is generated if glGenLists is executed
between the execution	of glBegin and the corresponding
execution of glEnd.
