/**
 * No upscaling dewarp policy. Dewarp height will be calculated in a way
 * that no part of image will be up-scaled. However, if dewarp height
 * calculated in this way is larger than value defined by maxAllowedDewarpHeight,
 * then maxAllowedDewarpHeight will be used for dewarp height, effectively scaling
 * down the image.
 *
 * This policy is usually best for processor groups that use DEEP OCR,
 * hologram detection or NN-based classification.
