[Vision Glass] UI to realign controller on startup

[felipeerias]

Display a dialog informing the user that it is necessary to point the phone straight ahead to set up the controller.

Clicking the realign button on it will re-calibrate the controller and close the dialog.

A similar dialog is displayed on the VR environment.

The code looks good but I though you were going to add a dialog to the virtual world and not to the phone UI. Something similar to the privacy dialog, something that users will see no matter what. The UI in the phone could be potentially completely overlooked. I'd like to know your opinion about that.

Code doesn't look bad but I think it has some behavioural and aesthetic issues issues issues

1. the font in the dialog is blurry, I guess because it has some shadow but it's difficult to read
2. the dialog does nothing until you click, so perhaps we should add something like "and click to calibrate" ?
3. the dialog is not autoclosed after 5s, it needs 10-15s sometimes and the calibration is not done

Apart from that we've talked about adding some visual indication in VR. As far as I see there is nothing about that yet.

The visual indication looks great. However I think we should disable the autoclose and force the user to click on the button. There is no time to read the text and do the action unless you're a pro user. So I think we should remove the autodismiss, and then we could land it.

OK so some more comments, sorry for the back and forth. This is what I experience now

1. the phone UI keeps dissapearing
2. the OK button in the glasses dialog maybe could be removed, otherwise users will try to click on it with an uncalibrated controller
3. we should probably describe a bit better what we expect from the user. The current text is good but we should also mention that once the phone is aligned they need to tap on the phone
4. last but not least calibration does not happen once the dialog is closed, you need to tap on the calibration button again.

BTW just to clarify, I think 4. does not require any action from you. I think we can fix it with my changes in #1421

Nice, LGTM

I'd suggest to add a text like the one I added to ask users to click on the align widget
