The current functionality discards all margins if any values fall
outside the minimum or maximum limits. This can confuse and
frustrate users since the Windows native page setup dialog doesn't
enforce minimum values.
Introduce a new parameter outOfBoundsPolicy for the set margins
functions in the QPageLayout:
- OutOfBoundsPolicy::Reject The old behavior rejecting out of
bounds values.
- OutOfBoundsPolicy::Clamp The new behavior for clamping the values.
The OutOfBoundsPolicy is applied only in StandardMode to maintain
backwards compatibility in FullPageMode, where all margins are
accepted.
Use the new Clamp policy in the printsupport where the clamping is
necessary.
Maintain binary compatibility by putting the declaration of the old
symbols without policy parameter behind QT_GUI_REMOVED_SINCE, and
implement them in removed_api.cpp to call the new versions.
