PILHelper._to_native_format() rotated images with Image.rotate()'s default expand=False, which keeps the original canvas size. For a square canvas (every existing device's key images) or a 0/180 degree rotation this is a no-op, but for a non-square canvas rotated by 90 or 270 degrees it silently clips the rotated content instead of growing the canvas to fit it. This is required to correctly support the Stream Deck + XL's touch window (1200x100) and full LCD panel (1280x800) images, which Elgato's protocol requires to be rotated 90 degrees counter-clockwise before upload. No behavioural change for any existing device.
Adds a new StreamDeckPlusXL device class implementing the Stream Deck + XL (36 keys in a 9x4 matrix, 6 rotary encoders, a touch-capable window strip, and a full LCD panel behind the keys), and registers its VID/PID (0x0FD9 / 0x00C6) with the DeviceManager. Implemented directly from Elgato's official HID protocol documentation: https://docs.elgato.com/streamdeck/hid/stream-deck-plus-xl https://docs.elgato.com/streamdeck/hid/general Key event, touchscreen event (TAP/PRESS/FLICK) and encoder event (BTN/ROTATE) parsing follow the same on-wire layout already used by the existing Stream Deck + implementation, just sized for 36 keys / 6 encoders. Button, touchscreen-window and full-screen images are all generated dynamically via PILHelper (instead of a hardcoded blank JPEG byte array), so they are always correct for this device's declared image formats -- including the 90 degree counter-clockwise rotation this device requires for its touchscreen and screen images. Note: the VID/PID and protocol details come from Elgato's published documentation; I don't have physical hardware to test against, so real-world verification (particularly key index ordering and image orientation) from someone with the device would be very welcome.
Mirrors example_plus.py: demonstrates per-key images, dial push/turn callbacks, drawing on the touchscreen window, and setting the full LCD panel image.

Claude helped me.
I'll test it as soon as my stream deck plus xl arrives
Edited: oh I haven't seen there is already a pull request for plus XL version.
Please ignore this one.
