Dimension mapping strategy

[axelboc]

So something like <App dimMappingStrategy="first" /> (with the default strategy being "last" and the typing being type DimMappingStrategy = 'first' | 'last';). I don't think we need anything more complicated, at least for your use case, right?

EDIT: The "locked dimensions" feature added in #1840 will impact this issue.
