Hi,

Firstly SVG-Edit is not made with high-resolution editing in mind. So a lot of 
its algorithms and code do not necessarily be as optimized and efficient as 
possible. I'm afraid your solution for now is to throw in more hardware (more 
RAM on your side) and hopefully that will resolve the error.

In my personal case with 4GB of RAM it was enough to play around in 10kx10k 
resolution. Although moving around will start to be laggy.

Closing this issue.

It's a browser limitation, I have 8 GB of RAM.
Chrome fails if the canvas height is greater than 32767 pixels. Firefox fails 
greater than 8192.

Please review this patch.
