Description

When using loadImage to load a JPEG image with orientation metadata, Processing seems to ignore it and renders the image in the wrong orientation. In my specific case, the image is showing upside down. I'm attaching a sample JPEG image with such attribute that is loaded upside down.

Research direction
Examine how Processing's loadImage function handles JPEG images and check if EXIF orientation is read. Look for any existing orientation handling code or potential missing implementation.
