Ok, I feel it is time for an update - the last entry in this diary now is one year old... :-)
In the meantime the thesis is finished, I am now Diplom-Mathematiker and have a job as scientific assistant in the Workgroup of Professor Merzenich (Programming Languages) at the University of Siegen. I moved to a new apartment, which is a great improvement over the old one.
The Path tool of The GIMP has made great steps forward, I am basically finetuning it now. It has been a huge amount of work, but when it started to work it simply kept rolling. It is nice to get something usable after the usability nightmare of the old "bezier select" tool.
It seems our reference artists share my opinion on that... :-)
Thanks to the work of neo it is now possible to import SVG-Paths into the Gimp, also it is possible to export Gimp-Paths as SVG. Vector-Layers definitely are becoming reality after the 2.0 release....
So basically life is good :-)
