The architecture here is a little bit convoluted. I ended up making a new container widget (TimelineContainer) that works similarly to GUI::ScrollableContainerWidget but has two subwidgets (a fixed header that only scrolls vertically, and the timeline view that scrolls on both axes.) It would be nice to generalize this mechanism eventually and move it back into LibGUI, but for now let's go with a special widget for Profiler so we can continue iterating on the GUI. :^)
