Update to light (patch #8943)
* gl-render.h, gl-render.cc (get_maxlights): New static function.
(opengl_renderer::max_lights): New data member.
(opengl_renderer::opengl_renderer): Use get_maxlights to initialize
max_lights data member.
(opengl_renderer::draw_all_lights): New function. Support local
light sources.
(opengl_renderer::draw_axes_children): Call draw_all_lights instead
of doing the work here.
(opengl_renderer::draw_surface): Remove warning for "phong".
* scripts/plot/draw/light.m: Update docstring. Add and update demos.
* doc/interpreter/genpropdoc.m: Update docstring.
