I've got one question about `vertical-motion': Why is it apparently
slower than `window-text-pixel-size'?

shr-vertical-motion                  854         2.0539825089  0.0024051317
shr-pixel-buffer-width               988         1.0268266620  0.0010392982

Would it be possible to get a "go to pixel position X on the current
line" function that's faster than the current `vertical-motion' function
if there are some ... assumptions we could make?  Or something?  :-)
