Crop of all of the Headsets is not tall enough

[GuillaumeLeroy34]

Describe the bug
The mirror of the headset is not tall enough, which leads to the image being cut notably at the bottom, preventing people outside of the helmet from seeing the very bottom of the screen, which may prove challenging in games where the player is asked to look on the floor for fruits or for trash for example.

To Reproduce
Steps to reproduce the behavior:

1. Start the application, with the headset of your choice connected to it through adb
2. Go to the headset streaming page
3. Compare the image from what you see inside the headset and on the screen: A very noticeable amount is cut from the bottom.

Expected behavior
The differences between what is displayed on the screen and inside the headsets should be minimal.

Screenshots
TBA

@GuillaumeLeroy34 I'm modifying the tags and the proposed solution :

The scrcpy cropping is made to match the full right eye of the headset, without cutting off the game view. However, because of scaling/display/UI/UX reasons, this canvas can be cropped leading to only display some un-interesting aspect of the streaming

Therefore, the problem doesn't come from the backend, but should be fixed by how the frontend scale/cut those streaming. This said, I'd recommend you to, instead of just leaving the default CSS positioning (top-left corner) to always set the display anchor in the middle of the div (centered vertically & horizontally) to fix this issue.
