As noted above the library is released under the Creative Commons Attribution-ShareAlike
4.0 licence. However, as a special dispensation you may use small portions of any shader
code, up to 8 lines, without any conditions, though I would prefer it if you acknowledge
their source in some way.

You may modify any shader in the libary for you own use and you may then redistibute it.
However, if you do then please rename it and add a comment at at the top of the shader's
source so that it is clear to any other user that is has been modified. This is intended
tp prevent the confusion that can arise when a wrong version is used by accident.
