In response to sad's remarks about the trust metric, yes it is really a respect metric. It only has the name trust metric because the original use for the algorithm was encryption key webs of trust. Advogato was an experiment using the same algorithms for a respect metric. I think raph mentioned this in some of the early advogato articles.
Looking at doing the expose/redraw code for DiaCanvasView's. I am implementing this with Federico's nice UTA manipulation routines from eog. The routines are GPL, but as Federico was talking about using them in GnomeCanvas, he probably won't mind relicencing to LGPL in the future.
Alex is focusing on the renderer interfaces It is an interesting problem where you want to cache data (eg. SVPs for a libart based renderer) on a view by view basis, but don't want to add any special case code for a particular renderer to canvas items.
