Am working on the first new Painting With Light feature for 2015, which is an upgrade to the line tools. They have always been a bit limited due to their width being stuck at a just a single pixel. This was due to the limitations of the underlying graphics driver but I’ve been planning to make their thickness controllable.
As you can see from the screenshot above, they are now working though there are some tweaks I’d like to see in future.
There will be a new release soon with this new feature in.
