[ENH] lock the aspect ratio

[marcobarilari]

if you enlarge/reduce it, at some point it loses the ratio proportion of height and width

but is that something we want to do?

I think that I set it so that it gets "stuck" on the edge of the screen.

Also it might be that the participant has FOV with a very strange aspect ration.

If I get your question, I would say no. We don't want the aspect ratio will be modified during this trial.

Yes, it gets stuck to one edge (e.g. left), but if you keep moving it towards that edge on dimension is shortened more and more (e.g. width)

Also it might be that the participant has FOV with a very strange aspect ratio.

True, so might be the case that we actually want to modify the aspect ratio, the question is how? We do not have so many buttons :)

Thankfully we have 2 buttons left !!!!
