//  dx,dy = destination x,y
//  sx,sy = source x,y
//  sw,sh = width and height of the copy
//  blitter = copying method, check blitters.h
//  parameter = if a blitter method needs a parameter pass it here,
//              else pass 0
//  Sample:
//  blit(source,dest,10,10,0,0,20,20,alphavalue_blit,128)
//  will blit the topleft 20x20 of source to 10,10 in dest,
//  blended ~50%  (128/255)
