The effect was: when drawing a shape on a single layer, all
layers have been redrawn. This was changed such that only
the affected layer is actually redrawn.
* The solution consists of attaching a bridge object
to QObjects. If the host object is destroyed, the
bridge object will notify the script client
* The bridge object attachment is optimized so it
only happens if required (but still too often ...)
* The child object of QChildEvent gets a special
handling since this object is almost dead in case
of remove. This special handling consists of
a special, stripped class which is used to
only represent QObject in that particular case.
* Refactoring: no more "box+exclude" regions - they
can be emulated using a NOT with the same result
* "confinement" of regions inside recursive shape
iterators
* setters and getters for complex regions in GSI,
confinement
* more unit tests, some bug fixes
- Added some tests
- Performance improvements for insert of
regions into shapes
- Added LayoutLocker for that purpose
(locks a layout against updates temporarily)
- Improved implementation on RecursiveShapeIterator
with complex regions: will now check if a shape
is really inside the region.
