integration: add mixing tests

Browse source 
Add a new test that creates a given number of layers. Each layer has the same
assets / clips shifted by a different amount in the timeline. Alpha and volume
properties are different for each layer. This test is similar to the mixer
example in:

http://gist.github.com/MathieuDuponchelle/5736992#file-mixit-py

We should be able to add more clips to each layer, but this example test only
tests mixing 1 clip across 4 layers.
