+	material does not accept the zbuffer = true, it can set it to false.
+	This is useful, because in the next lastMaterial will be just the
+	material in this call.
+	\param lastMaterial: The material parameters which have been set before

+	\param resetAllRenderstates: True if all renderstates should really be
+	reset. This is usually true if the last rendering mode was not a usual
+	3d rendering mode, but for example a 2d rendering mode.
+	You should reset really all renderstates if this is true, no matter if
+	the lastMaterial had some similar settings. This is used because in
+	most cases, some common renderstates are not changed if they are
+	already there, for example bilinear filtering, wireframe,
+	gouraudshading, lighting, zbuffer, zwriteenable, backfaceculling and
