Curious about this, I ran a test in LC 9 with a new stack with one 
button containing this script:

on mouseUp
    set the rect of me to 0,0,6000,6000
    put specialFolderPath("desktop")&"/TestBigImage.png" into tFile
    export snapshot from me to file tFile as PNG
end mouseUp

On Ubuntu 14.04 w/8GB RAM I get the image file generated within seconds, 
but then LC takes another several seconds (almost a full minute!) with 
one CPU core maxed until it goes back to a normal idle.

Worse, while writing this email I was switching back and forth between 
my email client and LC, and apparently resume also takes nearly a full 
minute of maxed CPU before I'm able to work.

I'll run strace with that and file a bug report later to see what could 
be done, but back to your app's need:

Is raster output the best option for your users?

Even at 10k px that'll be a pretty big file, unwieldy in many image apps 
(and apparently prohibitive to export in the Linux version of LC currently).

It would be tedious but not too difficult to write a CardToSVG function 
instead, giving your users a widely-supported vector format whose file 
will be only slightly larger than the stack it was generated from 
(relatively speaking; being a plain-text format I'd guess the output 
size would be a small multiple of the stack file size, but certainly far 
less than a raster representation of the same layout).

I know Alejandro had written some SVG importers some time ago - anyone 
here have at least the beginnings of an SVG exporter we could build upon 
as a community project?
