They have a really good implementation, and I suspect they make heavy use of mipmaps. For example, painting with a 500x brush on a 10000x10000 image when zoomed out is very snappy, and I don't see how they could do that without doing tricks with mipmap levels. Regarding automatically managing the size of layers, I totally agree that GIMP should do that boring work for the user, that's not something a user should have to worry about. / Martin -- My GIMP Blog: http://www.chromecode.com/ _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
