The present setting results in almost all cases in a recognizable
cursor position (images with border 0 are possible only come Emacs
22.1).
Are you saying that the problem of failing to show the cursor
only applies when the border is 0, and that that is a new feature?
In that case, let's limit my recommendations to the case when the
border is 0. We can give :mask a different default, or make the lack
of :mask an error, only when border is 0.
I have experienced that: trust me,
this default _is_ worse, much much worse than the existing one.
That makes no sense at all. The current default (in the case with
border 0) is not to show the cursor at all. (If I'm mistaken, please
explain.) If we change it to heuristic-mask, then usually it would
show the cursor. That is better than not showing the cursor.
If you want me to believe this is worse, you'll have to demonstrate it
with clear explanation, not emotional upset.
preview-latex had to go to quite disadvantageous techniques to avoid
large-scale flashing in Emacs 21. You'd reintroduce it.
Would you please show the justification for that claim?x
I think it would be a mistake to abuse :mask just in order to get the
cursor to display in a useful way.
There is no "abuse" in changing the default.
In particular since it would mean
that customizing the cursor type would have no effect on images,
Why do you think it would mean that?

It will also break wagonloads of existing code.
I doubt it. You've said border 0 is a new feature, so there can't
be so much existing code that uses it.
