No lines displayed at all if the first coordinate is out of bounds #47

Open dedeibel opened 6 years ago

dedeibel commented 6 years ago

I have a sketch were nothing is display.

I have debugged the problem so far that apparently the first coordinate is "out of bounds". The correction logic of the rendering will ignore those coordinates. But if the first coordinate is out of bounds it will see all the following coordinates as being out of bounds and therefore not draw anything.

I am currently working on a fix by looking at more than just the last and the current coordinate in order to make that decision.
