TS3.0-RC - VRLayer left/rightBounds type.

[cmerighi]

TypeScript Version: 3.0.0-rc
VRLayer type described in 3.0rc's lib.dom.d.ts conflicts with the one in @types/webvr-api. The latter is a devDependency for the widely used @types/three.

VRLayer in lib.dom.d.ts:

interface VRLayer {
    leftBounds?: number[] | Float32Array | null;
    rightBounds?: number[] | Float32Array | null;
    source?: HTMLCanvasElement | null;
}

VRLayer in @types/webvr_api/index.d.ts:

interface VRLayer {
    leftBounds?: number[] | null;
    rightBounds?: number[] | null;
    source?: HTMLCanvasElement | null;
}

Looking at the specs, including Float32Array among the piped types seems unnecessary/wrong to me.

This all came about due to an issue discussed in microsoft/TypeScript-DOM-lib-generator#419 where some browsers adopted earlier versions of the spec which required Float32Array.

Should be fixed by #25944

Is there a workaround for this issue in the meantime? Thanks!

EDIT: Worked around this issue by adding a new type roots folder, with webvr-api/index.d.ts and the Float32Array definition. Will subsequently drop this folder and the erroneous definition.
