fix (web): panorama / 360 view - partial panorama: use photo-sphere-viewer

[dmitry-brazhenko]

Previous PR: #3412

This PR should fix 2 issues: #3490 and #3465

I changed 360 images viewer. Now I use photo-sphere-viewer.

I checked "cropped/partial" panoramas and they work fine.

I don't merge PRs, only some people do :)
Why is it so urgent? It's not like we'll do a release right after this PR

[dmitry-brazhenko]

No urgency, just wanted not to forget about this :)

[danieldietzler]

We usually don't "forget" pull requests, no worries.

The photo-sphere-viewer documentation says that it handles cropped/partial panoramas by looking at image metadata. We strip most metadata from preview images now, so can you confirm that a newly uploaded partial panorama still works?

[alextran1502]

@mertalev tested on panorama taken on iPhone and it works

[dmitry-brazhenko]

Yep, I also tested on newly uploaded images. As far as I see, exif is not removed from image

[rovo89]

@dmitry-brazhenko I think panorama-viewer.css is now unused, isn't it? Then I guess it should be deleted.

[dmitry-brazhenko]

@rovo89 thanks a lot for your attentiveness!!

Here is a PR: #7012

A few comments...

• panorama photos got attributes InitialViewHeadingDegrees and InitialViewPitchDegrees, ignoring them causes that image is rotated to the wrong side initially, they should be kept and set to poseHeading and posePitch panorama viewer properties
• there is a white vertical line between info panel and panorama, it's because viewport of panorama has partial dimensions, but the viewer uses integer (truncated) ones

[dmitry-brazhenko]

That's good point. I created an issue: #7243
