The trees, that obstruct the view on the forest, can be allowed to fall! (Die Bäume, die die Sicht auf einen Wald versperren, dürfen gefällt werden!)

When dealing with float coordinates and their innaccuracy, == 0 doesn't mean much.

Integers don't help here. Integers are the corners of the pixels. To display a vertex point to display as a pixel, it needs to be in the centre of the pixel, not at its corner.
Make sure you read what eXpl0it3r's links above; it has a diagram and everything!
