Honestly, though, I’d be happy for you to have a look as we’re rather
struggling. Using the offscreen bitmap means Emacs doesn’t have any
odd graphical glitches. The other method, described here


does have serious glitches but has *much* better performance.

OK.  I'll see about spending some time in the area, see if I can't improve performance for me and hopefully everyone else.  Thanks for the pointers and patches, which I'll play around with, and see what comes of testing them, and additional profiling.

I can't promise a strict timeline, as this is a personal time project, but I'm definitely motivated to improve performance here.  I'll keep in touch via the list on progress.  Thank you for your quick response.
