Resources was a direct mapping of the QObject children.
This led to problems since the QObject children can also contain
other objects from other sources like attached properties.

This patch decouples resources from QObject properties
and also does not call setParent() anymore.

The special case for QQuickWindow in data_append does rely
on the fact that QObject::setParent() is called and the
inner window becomes a QObject::child of the content item.
So we keep the setParent for this special case.

The children property does not take QObject ownership either.
QObject ownership is handled by the VME.

None of the documented QML use cases should be touched by this change.

This is a cleaner solution then the ad hoc fix provided by
https://codereview.qt-project.org/#change,54677



I changed also the test. The list count now has to be exactly 4.

emitCap is intended to prevent issues with multiple emission of infinite
life particles, but it can currently prevent emission of any particles
when particleCount() changes after a reset. Tracking particleCount() on
changes would be inefficient and be more work to integrate with the
correct behavior of infinite particles, so this patch delays the impact
of emitCap until an infinite particle is discovered.

This will lead to a subtle behavior difference of limiting infinite
particle counts based on the count at the first emission, not the first
reset, which could be construed as a bug fix in some situations. This
seems reasonable as a futher subtle behavior change will be needed in
the future to properly support varying counts of infinite particles.

Fixed blur being too faint by fixing the weight to correctly match the
amount of pixels being sampled based on the blur radius, and by not
multiplying and flooring to int inside the sampling loop which leads to
excessive rounding down errors.

The "half" value in the previous implementation was also wrong due to
using integer division instead of floating point division, which caused
the blur being slightly offset down and to the right.

By not calling scanLine() and constScanline() repeatedly and by only
applying the weight once in the single-weight case we can also gain a
slight performance improvement.

Also, make sure blur radii below 2 don't get floored to 0.
