A custom effect provided by DPSF. In DPSF v2.1.0 and prior this effect was used as the default effect for all particle system types. Each particle system type now uses one of the built-in XNA 4 effects as its default effect in order to make all of the particle system types fully compatible with the Reach profile, and usable on the Windows Phone 7.
This effect may still be used for a particle system by calling the SetEffectAndTechnique() function from the particle system's overridden InitializeRenderProperties() function.
This Effect has several techniques that may be used (DPSFDefaultEffectTechniques).
