Most of the example titles have either a "Qt Quick Examples -" prefix or
a "Scene Graph -" prefix.
Also fixed a typo ("Scenegraph" -> "Scene Graph")

"qtquickexamples" is for illustrating code usage; "qtquickdemos" is for
showcasing fully-functional apps.
Renamed titles and screenshots to match the other demos.
Also, attempt to make the descriptions sound more interesting.

When we're bundling Qt inside the apk, we need to know

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.

It can happen that when the QQmlDelegateModel goes away some of the
QQmlDelegateModelItem from d->m_cache are still incubating, this
means that isReferenced() will return true and we will not delete them.
This also means that when these QQDMIncubationTask finish they may end
up calling QQDMIncubationTask::statusChanged which will try to access
the delegate model that is already gone.
This commit makes sure we set vdm to 0 in these orphaned
QQDMIncubationTask so in QQDMIncubationTask::statusChanged we know
no one cares about us anymore and don't reference the already gone
delegate model

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.

If the item being rendered didn't have a bounding rect starting in the
origin the shadow path would be get an additional offset equal to the
distance of the item from the origin. Also, the stroke's shadow did not
take the pen width into account, causing clipping artifacts.
Combine all the common shadow generating code into a single function,
and avoid rendering into an intermediate image that is then blitted into
a larger image.

QJSEngine doesn't call collectGarbage upon deletion, because this

Fix some issues with incremental updates found while
playing with the Quick Controls textedit demo.
-Grouping text blocks into a single text node is fine as
long as it doesn't cross the boundary of a child frame
(e.g. a table), otherwise all that node logic collapses.
-Text tables are hard to split in a sensible way, ensure
we treat them as one text node for the sake of simplicity.
-Inline images can cause several text nodes to have the
same apparent start position. Beef up the rewinding logic
in markDirtyNodesForRange.
