- Collapsed the per-particle data into a single struct, and use that to communicate with drawables, too. Let the drawables manage allocation of xforms, colors, etc. Helpful for non-atlas drawables, and just to keep the effect code simpler. - Having all of the params in a single struct allows us to move the remaining animated behaviors into affectors (color/frame). - Added SkColorCurve, which works like SkCurve for SkColor4f. Use that to create a color affector (rather than simple start/end colors in the effect params). - Also put the stable random in SkParticleState. This is going to be necessary if/when we change affectors to operate on all particles (rather than one at a time). Still need to move t value into the particle struct (or eval it from the lifetime params on demand).
