Functions

calculateRatio	Calculates an integer scaling ratio common for X/Y axes (square pixels).
calculateRatios	Calculates integer scaling ratios potentially different for X/Y axes as a result of aspect-ratio correction (rectangular pixels).
calculateSize	Calculates size (width and height) of scaled image without aspect-ratio correction (square pixels).
calculateSizeCorrected	Calculates size (width and height) of scaled image with aspect-ratio correction (rectangular pixels).
calculateSizeCorrectedPerfectY	Calculates size (width and height) of scaled image with aspect-ratio correction with integer vertical scaling ratio, but fractional horizontal scaling ratio for the purpose of achieving precise aspect ratio while still having integer vertical scaling e.g. for uniform scanlines.
