Poor display on Macbook Pro with retina screen
The current version of sage-view yields very pixel-mated output on Macbook Pro with a Retina display. Since Emacs 24 is retina ready, this feels very uncomfortable when making sage calculations within Emacs.
I suppose the poor display problem may stem from the conversion from PDF to png images. However, having practiced with various combinations of gs parameters, I have got no satisfactory resolution. A command line test indicates that using pngalpha instead of png16m as output device and adding -r144 as instruction for resolution gives must better output. But I don't know how to pass the -r144 parameter from inside sage-view.
