Extremely large images may take hundred(s?) of gigabytes of ram #508

50k x 50k image managed to take 115.4 GB of ram while testing #506 last week. I'm pretty sure it just keeps growing until Oculante crashes or the system runs out of memory.

@B-LechCode Pinging you here for this in-case you have any ideas of what's causing this.

50k x 50k x 4 x 1 byte = 10 GB RAM per image. So it shouldn't go above 50 GB: Reading image, Normal Buffer, Edit Buffer, Copying sub images and the texture itself

Which image did you use to "achieve" this?
