1.2.1

Fixed a spelling error - minimumScaleMultiplier has more 'i's than I gave it.

1.2.0

• Added acceleration - a pair of x/y values of constant acceleration of particles to simulate gravity or other forces. This overrides any interpolation of speed, although the start speed is still used for the initial velocity of a particle. If rotationSpeed is 0, then the rotation of the particles are set to match their direction of travel.
• Added minimumScaleMultiplier - a value that allows you to have random variation in scale of your particles that does not interfere with scale interpolation. A random multiplier is generated for each particle between minimumScaleMultiplier and 1, and applied to both start and end scale for that particle.

1.1.2

Fixed an issue with custom eases.

1.1.1

Added blend mode support.

1.1.0

Made the particle system more extendable by providing your own subclasses of Particle.
