For the aliasing issue, the solution is the same as the image downscaling: add supersampling to pixman. The various image fetchers should fetch a grid of subpixels for each output pixel and then compute the average before storing the result in the output buffer. (The fact that supersampling applies to both gradients and sampled images (and to a future polygon image) is one of the main reasons to use it rather than more sophisticated area sampling techniques).
