Taking screenshots on Triple 8K monitors crashes zdoom

You can test this out by setting the custom resolution to 23040 x 4320. Single 8K monitors take screenshots just fine. Triple 4K works fine too.

GZDoom depends on a predefined maximum screen width because a few buffers need this statically. The current value here is 12000, of course triple 8K is way above this limit, which was set to this for triple 4K.

Given how few people can actually afford the setup described here, I don't think it is worth the effort to do something about those fixed arrays. While we are at it, 23k is pretty close to 32k where a new can of worms opens when 16 bit signed integers no longer fits.

Right - but I think the fixed size buffer in the PNG writing code can and should actually be fixed - the rest is either in the software renderer and in the PCX screenshot code which I might remove entirely because - who is still using such an ancient image format...?
