| |
| Note that when converting a colour from regular LSL space (sRGB) to linear space for use in a light, it's likely quicker and cleaner to use the internal function [[llsRGB2Linear]]. This is mostly a function that can be used for fun to manipulate the gamma space of colours.

| Converts a gamma-encoded color value to linear space. Useful when dealing with lights (as these expect a non-gamma-encoded color).
