\inqmlmodule QtQuick.Particles
\brief Represents particles manipulated by emitters and affectors.
\ingroup qtquick-particles
Particle elements are always managed internally by the ParticleSystem and cannot be created in QML.
However, sometimes they are exposed via signals so as to allow arbitrary changes to the particle state
*/

than determining and changing the value at a given time. Change initial
values in CustomEmitters instead of the current values.

\qmlproperty real QtQuick.Particles::Particle::initialVX
The x velocity of the particle at the beginning of its lifetime.

Degrees clockwise per second that the particle image is rotated at while alive.

\qmlproperty bool QtQuick.Particles::Particle::autoRotate
If autoRotate is true, then the particle's rotation will be
set so that it faces the direction of travel, plus any
rotation from the rotation or rotationVelocity properties.
