ardour/gtk2_ardour/port_matrix_column_labels.h
Carl Hetherington 1a44701643 Fix a couple of crashes with empty matrices. Some small optimisations.
Correctly handle descenders on text when plotting labels.  Minor layout
improvements.  Add some drawings of what's going on in the port matrix
so that I don't keep losing them.
