\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
*/

\qmlproperty real QtQuick.Particles::Particle::initialX
The x coordinate of the particle at the beginning of its lifetime.
The method of simulation prefers to have the initial values changed, rather
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.
The method of simulation prefers to have the initial values changed, rather
than determining and changing the value at a given time. Change initial
values in CustomEmitters instead of the current values.
