I certainly like the simplicity of this approach. And it appears to explicitly cover the needs that I mentioned without any API changes. For example, for the logo I intend to follow what example 30 does where plshades is used to draw a rectangle with a large number of levels of different transparency to approximate smoothly varying transparency. However, once the above change was implemented, many fewer levels (in fact, only 2 for example 30) would have to be defined to get a smooth result out of plshades for devices that had native gradient capability.
