Bug 1995404 [wpt PR 55552] - WebXR Layers API: Add layer IDs to frame submit sequence, a=testonly
Automatic update from web-platform-tests
WebXR Layers API: Add layer IDs to frame submit sequence
This change introduces layer ids to the XR frame submission process via
mojom api.
The key changes are:
- vr_service.mojom: The SubmitFrameDrawnIntoTexture method now includes a layer_ids argument.This allows the VR service to receive a list of layers which modified shared buffer image for the current frame.
- XrFrameProvider: The frame submission sequence is now consists of multiple steps: ClearCachedLayersData -> SubmitLayer (for each layer) -> SubmitFrame.This new sequence allow us to collect layer ids, when 'layers' feature enabled and submit frame with a sing gfx::SyncToken.
- XRSession: The behavior of updateRenderState has been extended to support a layers feature. On ApplyPendingRenderState, if a modification to the layers composition sequence is detected, the current frame is dropped. The session then should update the layers sequence via the mojom layer manager API and requests a new frame.
