1237328 - [webvr] Enter VR fullscreen mode without user input

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Daosheng Mu[:daoshengmu]]

We would like to make VR display can enter to fullscreen without userinput. Currently, we will get nsContentUtils::IsRequestFullScreenAllowed false while it doesn't use userInput to enter the fullscreen mode.

Checking if it is vrDisplay first and then checking fullscreen error. If it has a fullscreen error and it is not vrDisplay, it will not enter fullscreen. So vrDisplay can enter fullscreen directly.

In next update, I need to check WebVR API whether it's enabled. If it is enabled, allowing elements to enter fullscreen.

<iframe> does not work for this patch now. I need to fix it as well.

V2: 
Renaming variable and making sure this patch works for iframe as well. For now, we needn't check gfxPrefs::VREnabled() because fsOptions.mVrDisplay is only assigned after dom.vr.enable is true.

We no longer use the full screen API to enter VR mode with the landing on WebVR 1.0.
