Sorry for the long title, but I'm wondering if someone has ever used a non standard output, different than the classic power of two e.g. 256x256, 512x512, 1024x1024 and so on.
In particular I'd like to have an output of 1000x1000 to ease some calculations on game engine world units, but the program warns you of "unusual behavior with some devices". Strangely enough the warning is only on tiled builds, not on normal ones.
I don't want to find nasty surprises later on, what's your opinion on this kind of output?
