Nice solution. I presume [FloatingType] allows for the struct to be initialized
with a real literal, whereas just using [SimpleType] means it has to use the
struct syntax. So
dReal x = 1.23456;
instead of
dReal x = { 1.23456 );

In terms of Vala syntax I think [FloatingType], [IntegerType] and [BooleanType]
enable the use of the relevant Vala literal syntax when initializing the
struct. I'm not so sure about the implicit casting rules in Vala, is the rank
detail required? There is also a width detail.
In terms of the C code generated the glib-2.0.vapi also has CCode details for
'default_value' and for doubles 'type_signature'. Not sure how relevant they
are.
It would be nice to get my understanding of [FloatingType], [IntegerType] and
[BooleanType] nailed and I'll try updating the Simple Types section of the
Legacy Bindings doc.
