Gallery::Imagery Layers Split

Hi, A little suggestion: https://pasu.github.io/ExamplesforCesium/examples/examples.html#Visualization-Planet I make this demo Imagery Layers Split, which is similiar with Cesiums’. One day I browsed this demo and found it did not support touch event Here is my modification and I tested it was fine:

document.getElementById(‘slider’).addEventListener(‘mousedown’, mouseDown, false); document.getElementById(‘slider’).addEventListener(‘touchstart’, mouseDown, false); window.addEventListener(‘mouseup’, mouseUp, false); window.addEventListener(‘touchend’, mouseUp, false);

function mouseUp() {
  window.removeEventListener('mousemove', sliderMove, true);
  window.removeEventListener('touchmove', sliderMove, true);
}

function mouseDown(e) {
  var slider = document.getElementById('slider');
  var nPos = e.clientX != undefined?e.clientX:e.changedTouches[0].clientX;
  dragStartX = nPos - slider.offsetLeft;
  window.addEventListener('mousemove', sliderMove, true);
  window.addEventListener('touchmove', sliderMove, true);
}

function sliderMove(e) {
  var slider = document.getElementById('slider');
  var nPos = e.clientX != undefined?e.clientX:e.changedTouches[0].clientX;
  var splitPosition = (nPos - dragStartX) / slider.parentElement.offsetWidth;
  slider.style.left = 100.0 * splitPosition + "%";
  viewer.scene.imagerySplitPosition = splitPosition;
}

I think the Sandcastle cleanup could be separate from #5780. Sounds like it should wait for that one to get merged first.

Yes, I registered CLA😄 Now, I am pulling another request #5780 . When I committed this html page, it would cause errors for the CI test, so I had to rollback the code for the Reviewers. And I largely believe there is nothing wrong with my code. So would you like to commit this for me or when cesium close the current request #5780, I promise to commit it later. Either is OK to me. I really hope to make more contributions to this great team. Attachment is Imagery Layers Split.html. Imagery Layers Split.html.txt
