For percent-based clipping fragments, it makes sense at all resolutions
(but perhaps having them integer-based is sub-optimal in many cases), but
for pixel-based ones, it is impossible to know the intent.
Does the format as a "default" version to apply the pixel clipping to? the
first one? last one? bigger one? The one that fit the display?
So it's not that it's hard, I just don't see how this could work reliably.
