Bartlomiej Niechwiej	e94338f4c6	Fix a drawing lag during track recording. For a track with ~2,500 points, the average drawign would take ~30-50ms, now it takes about 20ms (21ms if software clipping is enabled). Removed all possible congestion points by introducing a blocking queue. This change includes many fixes, including: 1) Major refactoring and clean up of the overlay, sped up drawing by a factor of 2x 2) Disable software clipping as it was slower by about 5% than w/o clipping and would trigger a bug related to map view spanning 3) Add waypoints synchronization and fixed a bug related to skipping the first wpt 4) Add a simple unit test	2010-10-11 21:55:12 -07:00
