Should the blend tool use premultiplied alpha for custom gradients? Make a custom gradient that is white on one end and transparent on the other. (Go on, use the RGBA 0, 0, 0, 0 option provided on the menu.) Now use it with the blend tool on a white canvas. The result is a gray band. In comparison, with the foreground set to white, use the blend tool's "FG to Transparent" on a white canvas. Isn't that better? So, I'd call the lack of premultiplied alpha for custom gradients a bug. But I seem to recall a recent debate about when it was and wasn't appropriate for gimp to use premultiplied alpha, so I figured I'd ask first.
