Thanks for your contribution! Please excuse my late response.

I do not quite understand your conditions in rectInteresects. For example in line 89: why do you add 1 on the left side of the comparison? Why is it not just rt1.x1 > rt1.x2?

Also I find the code quite difficult to understand, since you first assign both l1 and r1 the same value and change one of them afterwards depending on the condition. I would find it easier to understand, if both variables were assigned after evaluating the condition.

If adding 1 (see above) is wrong in the end, the code would boil down to l1 = min(rt1.x1, rt1.x2); r1 = max(rt1.x1, rt1.x2);. But then also the potential swapping of .x1 and .x2 would never occur, because it is already guaranteed on the calling side that .x1 <= .x2.

Why is the function called rectIntersects and not, e.g., rectsIntersect? Since two rects are checked for intersection I would expect plural.

Last, but not least, please use tabs for indentation like in the rest of the code.
