Events with duration == 0 were erroneously filtered out by the items
render pass. Also, we have to give them a very small width in order for
the "stretching" mechanism in the vertex shader to work.

If you insert events with equal start times in a way that the model can
not reorder them by their end times the parenting follows the indexes,
not the end times. This has caused confusion multiple times and it's
good to test it.

Allow models to be created without a parent and provide default
implementations for virtual methods. It's actually fine to have all
ranges in row 0 and in black by default. Having default implementations
makes things easier to test.
