Issue #1619 - Convert Intrinsic Ratio to Float
https://bugzilla.mozilla.org/show_bug.cgi?id=1547792 Aspect Ratio handling simplified by using floating point integers: - Multiplication of value (or inverse value) to a known side for Scaling - No unequal equal values such as "4/3" vs "8/6" vs "20/15" - Truly "Empty" aspect ratios, even if one dimension is not 0
