when marker is selected, then it's name is highlighted and name is moved up. It can be useful, when you have many named markers in timeline.

imemarker name is moved up, when current frame equals to frame of timemarker

name of marker is printed only when strlen(marker->name) is bigger then zero

name of marker isn't pushed out of window, when timeline window isn't very high
