9a1d7d74cb Improved performance for remote plotting:
- reduced cost of transferring arrays between processes (pickle is too slow)
  - avoid unnecessary synchronous calls

Added RemoteSpeedTest example

8355e6148d Performance improvements:
- AxisItem shows 2 tick levels instead of 3
  - Lots of boundingRect and dataBounds caching
    (improves ViewBox auto-range performance, especially with multiple plots)
  - GraphicsScene avoids testing for hover intersections with non-hoverable items
    (much less slowdown when moving mouse over plots)
These are deep changes; need good testing before we release them.
