New tiles system in GSV & threejs update

[Makio64]

Hi, thanks for this helper!

Apparently the new panorama tiles system use much more tiles and higher quality so the getTileData send wrong value and the panorama show up only 1/4 of the full image.

Example at let location = [48.8296942, 2.2615041]

Quick fix before exploring more the problem on a larger panorama sets.

//getPanoramaTiles
var data = getTileData(zoom, opt.tiles)
data.rows*=2
data.columns*=2

gl.bindTexture(gl.TEXTURE_2D, handle)
gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, 8192, 4096,0, gl.RGBA, gl.UNSIGNED_BYTE, null)

also to make the gpu example work for the current threejs ( v117 )

renderer.initTexture(tex)
let gl = renderer.getContext()
let handle = renderer.properties.get(tex).__webglTexture
