I've closed the survey this morning, and here are the results:

Crystal:
Adjust 15 83%
I don't think that this icon fits with my other choices 3 17%
Galaxy:
Adjust 4 21%
Zoom optimal 15 79%
HiContrast:
Please, help to choose which of these existent icons for each theme
should be kept to represent the command 'Zoom optimal'
Zoom optimal means 'Zoom to fit in window'.
Until recently, some LibreOffice modules used three different names for
this same action, and used two different icons for that.
