Splash is a rasterization engine. pdftops rasterizes files when detects that 
the conversion to PS will fail (e.g. the PDF file has some features PS does 
not support). So if you don't compile Splash you'll have PS files that are 
broken (OTOH the detection of that the conversion will fail is sometimes a bit 
too aggresive and there are some files that are rasterized when there is no 
need).
