  The problem is exactly the same as with antialiasing: Preclipping
will always produce nice and smooth results (which is what people
usually want) but subpixel-sized brighter-than-1 details will be more
or less lost. Postclipping behaves in the exact opposite way:
Subpixel-sized details will show up, but brighter-than-1 pixels
will have ugly aliasing artifacts.
  The former works ok in 99.9% of cases but is still not perfect.
