Actually, the proposed triangulated mesh in SVG won't buy us much at all, because we can just as well approximate a bezier-based AI-like mesh with small triangles or (better) beziergon paths right now (see http://inkscape.org/screenshots/gallery/inkscape-0.45-gradient-mesh-experime...), and it won't be _much_ worse or less efficient than if we used the triangulated mesh.
There's a decent chance of being able to exploit hardware acceleration for the triangulated mesh case; we don't get the same advantage from blurring a grid of shapes that had to go through the full SVG rendering pipeline.
found use for such gradients. A few times I thought I might use them, but when I actually tried, they always turned out too awkard, too sharp near the corners, too linear.
Hmm, I was a bit worried about that being an issue -- that is a known shortcoming of Gouraud interpolation. If we're wiling to sacrifice direct PS/PDF compatibility, we could possibly use a different interpolation function.
