To make scrolling (even of images or lines of widely different height)
reliable, compute-motion would need to pay attention to every display
element and parameter, including things like frame-local face properties.
So either it re-implements the redisplay or it reuses the redisplay.
The display mechanism at C level is already designed to facilitate
this. It's just a matter of adapting the higher levels to use it.
If this was already done for vertical-motion, it can surely be done
for compute-motion.
> IMO, compute-motion is too cumbersome to use.
The facility is essential. The idea of eliminating it makes no sense.
I don't know of a way to make it simpler to use, but I would be glad
if it were.
(The C-level mechanism has similar complexities in its interface.
They are simply necessary.)
