Other raster application, including GIMP 2.8, are doing OK performance
wise with a rendering mode that is very similar to GIMP uses now, so I
don´t we necessarily need to do drastic changes there in order to fix
the performance.

I think a useful GSoC project would be to define and implement some
meaningful benchmarks for GIMP. If successful, that would give
insights into what the causes of the current performance problems are.
I believe that is needed for coming up with a good solution for
current, and future performance issues.
