Specifies an alignment for this component.
Specifies an alignment for this component. May only be used inside a parallel group.
the alignment to use
Specifies that this component should be used to calculate the baseline of its surrounding group, which must be sequential.
Specifies that this component should be used to calculate the baseline of its surrounding group, which must be sequential. This is needed to align that sequential group along the baseline of a baseline-aligned parallel group that surrounds it.
Only *one* component in a sequential group should be marked this way. If there are several, the last one marked will be used.
Wraps an arbitrary component to allow for custom size constraints.
