 Bilinear resampling is used for rendering raster markers. So if the markers are scaled to a size that is not cleanly divisible into the original size then resampling will not produce a crisp result.
 
-With SVG rendering the same kind of blurryness can result if the final rendered dimensions of the svg are not cleanly divisible. This is a common problem if you attempt to set the width/height of a marker symbolizer using svg because the scaling is done against the bounding box of the svg paths (see below for more details).
