some parameters, like "spatial kernel sigma" or "range kernel sigma" or "alfa" or "beta" are dependend on output resolution.
While I make good image on "1024x 768" with "Fattal", the image on full resolution is very ugly. This is not very user friendly feature.
What can be done about it?
1) The algorithms could be changed not to be resolution dependent.
2) The resolution dependent parameters could be changed with change of resolution to reduce the effect of resolution.
3) There could be information about how it works and resolution dependent parameters could be marked.
4) There could be possibility to render detail of resulting image in full resolution instead of whole image at reduced resolution.
