added option for image interpolation #52

Closed gargantuan closed 9 years ago

gargantuan commented 9 years ago

The default image interpolation setting ('grid') was causing my non-retina sprites to look janky. So I added an option which takes any of the following values...

nearest-neighbor
moving-average
linear
grid
cubic
lanczos

Basically just exposing the lwip interpolation options through the css-sprite options. I found the grid interpolation wasn't right for the icon set I'm working with at the moment.
