[PD] Drawing lines in gem with alpha fade

[James Dunn]

Thanks - it's interesting but doesn't seem to do quite what I need. Even 
with a maximum alpha value, I still want the lines to stay on full 
brightness for longer. Also, I'm drawing some fine lines and there are 
some weird artefacts like blocks appearing in the trail. Is there 
something else I could try?
