Those "pxs" here shouldn't take place.

The max height or width for a canvas seems to be 32768 (which I
thought was enough).
This works :
{{{
<body onload="draw();">
}}}
You need to use a correct HTML/CSS syntax in order to make it work.

work.

As weird as it is, the HTML properties "width" and "height" don't seem
to support support values more than 32767 (16bits/2 - 1).
This works :
<canvas id="cv" width="32767" height="150"></canvas>
And the rectangle will be really 20*20px. It seems the style attribute
