Although DistinctNumeric, which is supposed to abstract the underlying type, was used to represent CSSPixels, we have a whole bunch of places in the layout code that assume CSSPixels::value() returns a floating-point type. This assumption makes it difficult to replace the underlying type in CSSPixels with a non-floating type. To make it easier to transition CSSPixels to fixed-point math, one step we can take is to prevent access to the underlying type using value() and instead use explicit conversions with the to_float(), to_double(), and to_int() methods.
