WriteOIIO: Crash in OIIO when writing large image

[rodlie]

Adding this now so I don't forget

I'm currently compositing large images at work that will be used in an 360 viewer. The final output image is 17814 x 8907 in either TIFF or JPEG. The actual comp is simple, I add two layers from an EXR (rendered in Blender) on top of a background image.

Any image format using WriteOIIO crash (in OpenImageIO lib, I don't have debug info on that library). The only image format I can use is PNG, as it does not use WriteOIIO.

Tested RB-2.5/RB-2.6 on Windows 10 and Ubuntu 22.04.

Will update with more info (when I get the time to build OIIO with debug info etc).

Can you check that using oiio from Python or the CLI is able to create such an image (e.g. resize an existing image)?
