[Bf-docboard] Typo Fixes for Lighting>Volumetric Lighting

[Eric Oberlander]

Hi

Can I suggest these changes to the section_VolumetricLight.xml ?

On line 8:
'rays become visible because of light' instead of
'rays becomes visible for the light'

On line 68:
'with a step defined by' instead of
'with a step defined bi'

On line 70:
'gives finer stepping, and hence better results' instead of
'gives the finer stepping an hence the better results'

On line 73:
(<xref linkend="BSG.LIG.F.S68.307"/>) .</para>
               remove the space here ^ to avoid an orphan dot/point.

Kind regards.

Eric
