loadFromJSON v6

[brianp70x]

render does not seem to occur after loadFromJSON, objects are not visible until canvas is clicked .

using version v6

Example @ https://jsfiddle.net/brianp70/8xry0meb/22/
buttons below canvas...
1st: click "stringify and clear"

2nd: click "Reload" method 1 or 2

loadFromJSON has been an Promise in v6, you should not call canvas.renderAll() as callback anymore

now you should use

canvas.loadFromJSON(json).then(function(){canvas.renderAll()})

does this also apply to loadSVGFromURL?

[mtrabelsi]

you can hover on it on vs code, it will show if it a promise or not...

All the functions have been moved to promise, we don't have callbacks anymore, or we shouldn't at least.
