Tempo Edit Density and Linearity Display Mode

When the Tempo Edit Density setting (in the Tempo Editor) and the Linearity Display Mode setting are both set to either a Bars|Beats Time Scale or to an absolute Time Scale, Tempo edits appear evenly spaced. When the Tempo Edit Density setting and the Linearity Display Mode setting are set so that one is set to an absolute Time Scale and the other is set to a Bars|Beats Time Scale, the number of Tempo edits appear to increase or decrease over time (against absolute time).
