// This is needed because the initial mComputedBorder value is set to zero.

// In order to compute stuff, we start from the initial struct, and keep

//
// That means, effectively, that when we set border-style to something
// non-hidden, we should use the initial border instead.
//
// Servo stores the initial border-width in the initial struct, and then
// adjusts as needed in the fixup phase. This means that the initial struct
// is technically not valid without fixups, and that you lose pretty much
// any sharing of the initial struct, which is kind of unfortunate.
//
// Gecko has two fields for this, one that stores the "specified" border,
// and other that stores the actual computed one. That means that when we
// set border-style, border-width may change and we need to sync back to the
// specified one. This is what this function does.
//
// Note that this doesn't impose any dependency in the order of computation
// of the properties. This is only relevant if border-style is specified,
// but border-width isn't. If border-width is specified at some point, the
// two mBorder and mComputedBorder fields would be the same already.
//

// just copy the specified border here, we'll adjust it if it's incorrect

/// scriptlevel is a property that affects how font-size is inherited. If scriptlevel is
/// +1, for example, it will inherit as the script size multiplier times
/// the parent font. This does not affect cases where the font-size is
/// explicitly set.
///
/// However, this transformation is not allowed to reduce the size below
/// scriptminsize. If this inheritance will reduce it to below
/// scriptminsize, it will be set to scriptminsize or the parent size,
/// whichever is smaller (the parent size could be smaller than the min size
/// because it was explicitly specified).
///
/// Now, within a node that has inherited a font-size which was
/// crossing scriptminsize once the scriptlevel was applied, a negative
/// scriptlevel may be used to increase the size again.
///
/// This should work, however if we have already been capped by the
/// scriptminsize multiple times, this can lead to a jump in the size.
///
/// For example, if we have text of the form:
///
/// huge large medium small tiny reallytiny tiny small medium huge
///
/// which is represented by progressive nesting and scriptlevel values of
/// +1 till the center after which the scriptlevel is -1, the "tiny"s should
/// be the same size, as should be the "small"s and "medium"s, etc.
///
/// However, if scriptminsize kicked it at around "medium", then
/// medium/tiny/reallytiny will all be the same size (the min size).
/// A -1 scriptlevel change after this will increase the min size by the
/// multiplier, making the second tiny larger than medium.
///
/// Instead, we wish for the second "tiny" to still be capped by the script
/// level, and when we reach the second "large", it should be the same size
/// as the original one.
///
/// We do this by cascading two separate font sizes. The font size (mSize)
/// is the actual displayed font size. The unconstrained font size
/// (mScriptUnconstrainedSize) is the font size in the situation where
/// scriptminsize never applied.
///
/// We calculate the proposed inherited font size based on scriptlevel and
/// the parent unconstrained size, instead of using the parent font size.
/// This is stored in the node's unconstrained size and will also be stored
/// in the font size provided that it is above the min size.
///
/// All of this only applies when inheriting. When the font size is
/// manually set, scriptminsize does not apply, and both the real and
/// unconstrained size are set to the explicit value. However, if the font
/// size is manually set to an em or percent unit, the unconstrained size
