Safari Panomarker movement

[Timtimsupertim]

In Safari (9.1, OS X El Capitan) the panomarker anchoring seems to be off when panning around. The marker moves around a bit. This is in Street View WebGL mode (as no other mode seems to work currently in Safari). In Chrome there is no issue, the marker moves as it should.

Comment this line
// this.povToPixel_ = !!window.chrome ? PanoMarker.povToPixel3d : PanoMarker.povToPixel2d;

And add this code below it

this.povToPixel_ = PanoMarker.povToPixel2d;
var pixelCanvas = document.createElement("canvas");

  
if (pixelCanvas && (pixelCanvas.getContext("experimental-webgl") || pixelCanvas.getContext("webgl"))) 
{
   this.povToPixel_ = PanoMarker.povToPixel3d;
}
