			<tt>glGenTextures</tt> returns <i><tt>n</tt></i> texture names in <i><tt>textures</tt></i>.
			There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the
			returned names was in use immediately before the call to <tt>glGenTextures</tt>.
		</p><p>
			The generated textures have no dimensionality; they assume the dimensionality of the texture target to which they are
			first bound (see <a href="glBindTexture.3G.xml">glBindTexture</a>).
		</p><p>
			Texture names returned by a call to <tt>glGenTextures</tt> are not returned by subsequent calls, unless
			they are first deleted with <a href="glDeleteTextures.3G.xml"><tt>glDeleteTextures</tt></a>.
