[Cin] Timeline borders

Dear developers! Now that you have done a tremendous amount of work to improve work with Cinelerra, you can pay attention to smaller issues. For example, to me personally, the border between the tracks is not at all obvious, especially when there are a lot of them. When the content is adjacent to the left side of the timeline, I understand where the border still somehow turns out (blue stroke). But in the absence of content, dealing with borders is much more difficult (red stroke).
