FTE's light builtins: getlight (the world's light at a point, 0 to 255 a channel,
as Cauldron3D.Bsp.Light.at/4 finds it), lightstyle with an optional colour,
getlightstyle (the pattern, and the colour through its second argument) and
getlightstylergb (the colour scaled by the pattern's brightness now, m being 1.03).
Colours are kept in the host's ext.lightstyle_rgb, style to {r, g, b}, white when
never given.
