Scaling issue

[CasualUser-12345]

Using the drawer while being zoomed in using Alt-Click leads to parallax between mouse and the line being drawn.
The same thin happens in full-screen mode.

Occurs in the demo page itself.

You can fix this by yourself.
Provide this code in your HTML:

function updateCanvasSize() {
    $("canvas.revealjs-drawer_canvas").attr("width" ,$("#sections").width());
    $("canvas.revealjs-drawer_canvas").attr("height", $("#sections").height());
}

$( window ).resize(function() {
    updateCanvasSize();
});
