Also introduce type dt_pickerpoint_t to store simple picker point.
Use the newly introduced routine to set the default which can be controlled in a single routine.
Again to ensure the default is set at a single point.
Ensure that the point position is preserved by using a new dt_pickerpoint_t variable (pdrag) when dragging a box corner. This also make it possible to swicth between point/area for all pickers. Closes #17887

Allow Ctrl+Clik on canvas to switch between picker point/area.
Ensure that the point position is preserved by using a new
variable (pdrag) when dragging a box corner.
This rework also make it possible to switch between point/area for all pickers.
Also use routine to initialize the picker point/area default at a single place. Better than having
the same code duplicated in many places.
Rework the picker initialization that do not require anymore a check for some values as the
picker point/area are now always initialized at creation time.
Finally a new type
dt_pickerpoint_tis introduce to store position of apicker point (we already add
dt_pickerbox_tfor an area).Closes #17887
