 598     \brief The ImageParticle element visualizes logical particles using an image
 599
 600     This element renders a logical particle as an image. The image can be
 601     \list
 602     \o colorized
 603     \o rotated
 604     \o deformed
 605     \o a sprite-based animation
 606     \endlist
 607
 608     ImageParticles implictly share data on particles if multiple ImageParticles are painting
 609     the same logical particle group. This is broken down along the four capabilities listed
 610     above. So if one ImageParticle defines data for rendering the particles in one of those
 611     capabilities, and the other does not, then both will draw the particles the same in that
 612     aspect automatically. This is primarily useful when there is some random variation on
 613     the particle which is supposed to stay with it when switching painters. If both ImageParticles
 614     define how they should appear for that aspect, they diverge and each appears as it is defined.
 615
 616     This sharing of data happens behind the scenes based off of whether properties were implicitly or explicitly
 617     set. One drawback of the current implementation is that it is only possible to reset the capabilities as a whole.
 618     So if you explicity set an attribute affecting color, such as redVariation, and then reset it (by setting redVariation
 619     to undefined), all color data will be reset and it will begin to have an implicit value of any shared color from
 620     other ImageParticles.
