For a lighter canvas, as previously discussed:

The canvas background color is now coded at lines 24 and 27 in the litegraph-editor.js file.
grid.png is no longer used.

Line 19 seems to be unnecessary (?). Commenting it out seems to do no harm(?)
line 19: // graphcanvas.background_image = "core/imgs/grid.png";

Max's line 24, commented out: // bgvctx.fillStyle = "rgb(62,62,62)";
Replaced for a Lighter color: bgvctx.fillStyle = "rgb(225,223,217)";


Max's line 27, commented out: // bgvctx.strokeStyle = "rgb(50,50,50)";
Replaced for a Lighter color: bgvctx.strokeStyle = "rgb(208,206,201)"

Also changed the cursor from "crosshair" to "default" in line 4 of litegraph.css.
