This can be handled by a good scaling algorithm. There are many 
possibilities...for example, the Mac program GraphicConverter offers 
these scaling algorithms:
QuickDraw/Quartz
Bicubic
Bicubic with dither
Smooth
Box
Triangle
Bell
B-Spline
Sinus
Lanczos 3
Mitchell

Manually blurring won't help much here, if at all. It really only helps 
with the "nearest neighbor" algorithm, which won't be used by any decent 
graphics program and would be useless for removing aliasing. I doubt 
there is any program that has a blur filter and which uses nearest 
neighbor, and blurring the source image will probably just interfere 
with these algorithms.
