UI issue: GPX not displayed properly

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Walk around the block until maps starts to scroll
2. Walk a few steps back, so the inital area scrolls back onto screen
3. You'll observe some strange display artifacts (basically unrelated gpx 
points are connected with a line)

What is the expected output? What do you see instead?

Please use labels and text to provide additional information.
The cause is that only visible gpx trackpoints are loaded and then connected 
according to their timestamp. So it might happen that some points are 
incorrectly connected (this is due to the fact, that only visible points are 
loaded, i.e. some points might be mssing)

Now loading gpx trackpoints for a larger area, thus the error should be gone in 
most cases (minor glitches are still possible, but for performance reasons that 
seems acceptable)
