Timeline: solve basic layout issue by properly calculating the height

As it turns out, we need to take the actual allocation of the cells within the grid explicitly into account: combined cells will report their extension for each of the underlying cells, thus leading to excessively overestimated measurements. So we now calculate the overall height based on the actual structure - first row holds the label - left column below used as expander - right column holds individual content Remaining problems: - height of ruler canvas at top not taken into account (11px in this example) - start of sub-track headers not synchronised with start of sub-tracks in the body area
