qt: add QT_COORD_TYPE to double option

Browse source 
On ARM-based platforms, qreal is a typedef for float for performance
reasons. But we may want a double precision anyway.

Set QT_COORD_TYPE to double. On ARM-based platforms, qreal
is a typedef for float for performance reasons, but for
QT_COORD_TYPE, some people may want to use a double type
anyway for precision.
If unsure say n.
