[Mesa3d-users] default light data

[Carlos P. <ca...@pe...>]

If I set the constant attenuation factor in a positional 
light (say Light0) to some value different from
1.0 (the default) and enable the light etc...

then disable the light and lighting (and color_material):

glDisable ((GLenum) GL_LIGHT0);

glDisable (GL_LIGHTING);
glDisable (GL_NORMALIZE);
glDisable (GL_COLOR_MATERIAL);

then create again the Light0 without saying nothing
about the attenuation factor, mesa (3.4) still uses the
non-default value I specified for the previous light0. 
Is this right? I thought Mesa would reset the light 
information in these situations... shall I explicitly
reset the light defaults myself in these cases, or is 
there some light data reset command that I am missing?

Thanks!

Carlos
