In Standard Assets ParticleSystem package sparks size in FireComplex and FireMobile prefabs is calculated incorrectly since 5.5.0f2.

To repro:
0. Install Unity and Standard Assets package.
1. Create a new project.
2. Import ParticleSystem package to Project.
3. Drag FireComplex or FireMobile to scene and press Play.

Actual result: Sparks size is calculated wrongly. See sparks_broken_in_550f2.gif attached.
Expected result: Sparks size is calculated correctly (like it was in 5.5.0f1). See sparks in 5.5.0f1.gif attached.

Regression since 5.5.0f2.
Looks correct in 5.5.0f1.
