Well, it's probably possible to implement conic gradients using GPU shader. But it's not possible at all to perform such things on small devices like phones. Or is it ? [Maybe the Opera-Mobile team's feedback could help us here] Having a linear-based solution would allow simple CPU emulation for those devices, while conic gradients seem more complex. Aditionnly, linear gradients are very simple and works pretty good, so I don't see why we should add more complexity here (except if you have a particular sample where a linear gradient would render badly). >From a web author point of view, gradient is desirable, but we don't care about how it's rendered (what only matters is that it's (nearly) the same rendering across all platforms and it's doesn't slow down our page rendering too much).
