Hi Lukas,

I'd like to put in a vote for the diffusion curves.  That stuff is very 
cool and looks very powerful for content creation.  Also it is nice and 
modular (self contained project).  But I would contact the authors first 
to clarrify their position WRT intellectual property.  I.e. Have they, 
or are they planning to patent this work and how will they view a GPLv3 
release of their work.

My second choice would be 3D brushes - also because they are relatively 
new and directly relate to content creation.  I'm not as familiar with 
this work however and assume a pressure sensitive pen device would be 
required to make good use of it?  If so it means the audience is smaller.

WRT advanced interpolation I think you should avoid this.  I have 
already done a lot of playing with advanced interpolation algorithms.  
Most are afflicted with subtle artefacts that are very difficult to 
avoid.  If you don't have a significant block of time and expertise to 
put into this you will find it very hard to do better than Lanczos 
(http://en.wikipedia.org/wiki/Lanczos_resampling).  This is also IP 
safe.  There is a lot of commercial interest in advanced interpolation 
for use in large screen TVs so the possibility for patent issues is higher.

Support for animation would be very cool but may be too ambitious at 
this time?  It would be far simpler to implement in a vector package 
than in a raster package IMHO.

Thanks for your efforts!
