ooh, that looks good. Very useful for interpolating data with faultlines, I guess.

I think suggestion #1 should be implemented in v.to.rast anyway, as it would be a functional improvement for many use cases where attribute values from vectors are to be transferred to a raster with DCELL/FCELL type cells. Your second suggestion would be an alternative, additional method with its own uses. Easily implemented, I imagine, by letting the user control the threshold (% of cell area crossed by line) above which a cell should be set to "1" (or whatever). In my scenario, a pixel should be placed, whenever the % crossed area > 0.0. The value to place could be the line value or an average of neighbouring cells. Both may have applications.
