[Bf-cycles] max render size?

[Brecht Van Lommel]

I can't immediately think of a limit that would make this render fail,
except for the amount of memory on your CPU being too low. It worked
for me on the CPU but I didn't look into it on the GPU yet. Some tips:

* Do not render with progressive refine in case you had it enabled.
* Use "Save Buffers" option in the performance panel.
* Disable the Z pass.
* Make sure you have enough swap space on your system.
