Watermark if Minimum Height

Conditional watermarking based on the minimum height of the rendered base image. If the height of the rendered base image is greater than or equal to the specified height, the watermark will be applied. If the height of the rendered base image is less than the specified height, the watermark will not be applied. The bare gate applies to every watermark layer by default; override it for a specific layer with mark-if-min-height[N].
