Why does the Clipper MegaCore Function have limitations on minimum frame width and height?

Why does the Clipper MegaCore Function have limitations on minimum frame width and height? Minimum image width is equal to 32 pixel. Minimum image height has the same limitation.

The original Avalon-ST Video protocol mandates 32x32 as the minimum frame size. This limit feels arbitrary but there is actually a technical reason for it. The first round of video IP was built with a HLS compiler that wouldn't pipeline loops if they did not have a minimum number of iterations.
