Tony, I had forgotten that there is a hard coded MAXPIXELS set at 32768. I think the only basis for it is that Tim thought it was suitably big. I'll have a look at it this weekend.

Any chance the current max render size of 32608,24456 might be removed or improved to allow for bigger sizes...? I'm hoping for at least 40k x 30x pixels, but even bigger would be great too - just for rendering L- systems as huge as possible...
I would suggest trying it. The disk video size is currently limited to a total of 4,294,967,295 pixels (xdots X ydots). This is the limit for an unsigned long integer. The code should shift over to using the hard drive from using RAM at a size of 2,147,483,647 pixels, the maximum size of a signed long integer. 40,000 X 40,000 = 1,600,000,000 pixels, so it should still work in RAM. It may look like it has locked up as it tries to clear all this memory before it starts to calculate the image. The clearing memory message seems to disappear now, instead of staying on the screen.
