TileMapServiceImageryProvider testing: various projections and extents from remote servers

CesiumJS
1

I’m testing some different tile map servers and running into tiling problems. I know that in this set of layers, they use at least 2 different kinds of projections and possibly more different extents. After getting the tiles to display, using a proxy as needed due to CORS (I used the node.js package ‘cors-proxy’), there is a tile problem in displaying the layers highlighted in red below. (the green are OK) I’m not expecting anyone to fix any of these but I am providing it in case Cesium developers want to experiment and/or expand the range of demo features. If I find a solution I’ll reply.
(This code has a lot of commented-out sections which aren’t necessarily meant to be activated all at once.)

btw here are some working WMS layers for NASA moon and Mars

var x = layers.addImageryProvider(new Cesium.WebMapServiceImageryProvider({

    url : 'http://webmap.lroc.asu.edu/',

// layers : ‘luna_clem750’,
//MOON
layers: ‘luna_wac_dtm’,
//MOON
// layers: ‘mars_viking’,
//MARS
