[Therion] XtTherion canvas zoom with the mouse wheel bug

[Bruce Mutton]

I think this feature was implemented mid-2017, and it was about then that I
raised the issue
<https://www.mail-archive.com/therion@speleo.sk/msg06518.html>  of a bug
with canvas zooming and bitmap background images.

There were a couple of commits
<https://github.com/therion/therion/search?q=zoom&type=Commits>  to resolve
this 25 June 2018, and the effect for me since then has been is that mouse
wheel zooming has been non-existent (although the code edits suggest
something should happen on wheel rotation).

So I am intrigued that you say it is working, even if very slowly.  I seem
to recall that the functionality was;

 

Ctrl+mouse-wheel to zoom in and out the XTherion canvas.

 

Currently version 5.4.4+bd62e22 does not respond at all to this control (and
it does it quickly ie no hint that a redraw is being attempted or that there
is an error condition).  Same behaviour for all versions (on Windows 10)
since 25 June 2018.  So what am I missing? How does one activate the mouse
wheel scrolling?  It is a nice feature (so long as its not too slow as Nick
has experienced).

5.4.4 seems to have cured this very annoying issue (so hard not to scroll)
but now with this latest release any scrolling is so ridiculously slow on my
Windows machine, I'm going back to 5.4.1 which scrolled fine. I will dig out
a none scroll wheel mouse for the few times I have to use a scanned image.
