Let me admit my ignorance here: for computer-generated raster graphics, I don't understand what DPI might even *mean*. Let's say I use Sage to make an images that 500 pixels by 500 pixels. To assign a meaningful dots-per-inch value, you need to have an idea of how large the image should appear. That seems ill-defined to me: the monitor I'm using right now is around 90 dpi; my Nexus S smartphone is 233 dpi. (I'm assume "dot" = "pixel".) How can Sage know the properties of the physical display, or what the user wants? Maybe there's some standard or mechanism that I don't know about, but it seems like this is something we can't solve for the user.
