[Suggestion] Adding mode for 3:4 image in a 9:16 framebuffer for the Move?

[Cinnamoni]

Suggesting a mode for rendering a 3:4 image on a 9:16 framebuffer for the Move for compatibility with older apps.
For the Move the image would be 954 X 1272 and be rendered with a "chin" on the bottom of 424px so you can use the bottom of the screen to hold the device.

Hoping to see this working. Not having KoReader on the Remarkable Paper Pro Move would make me to sad
