[XR][OpenVR] ScreenPointToRay() is offset when used in VR
Steps to reproduce:
1. Download and open the attached project
2. Enter playmode in VR
3. Set aspect ratio to "Remote" if not done automatically
4. Position HMD to look at any of the sphere objects
5. Focus Game view and move the mouse on any of them
Expected result: a raycast is registered and the sphere dissapears
Actual result: the raycast does not hit exactly where the objects are, but in the area around them
Reproduced on 2017.4.15f1, 2018.2.16f1, 2018.3.0b10, 2019.1.0a9
Notes:
- Only reproducible on OpenVR SDK, not on Oculus SDK

This solution does not work in free aspect ratio.

Resolution Note:
The root of the problem is that what you see in the gameview window if cropped : it's only 70% of the whole image (only for SteamVR).
With this knowledge, you can easily adjust your code to fix the issue :
var screenPos = Vector3.zero;
screenPos.x = 0.15f * camera.pixelWidth + 0.7f * Input.mousePosition.x;
screenPos.y = 0.15f * camera.pixelHeight + 0.7f * Input.mousePosition.y;
Ray ray = camera.ScreenPointToRay(screenPos, camera.stereoActiveEye);
