Panel should follow the 'text-scaling-factor' property

I'm running Unity on a rMBP 13". I need to set the text-scaling-factor to something like 1.6 to make the desktop usable. The problem is that the Panel is hard-coded to 24 pixels and the text is almost clipped in the panel.

I change the PanelStyle.panel_height to 24*1.6 and it looked good. My question is if you would like a patch which makes the panel height follow the font height or use 24*text-scaling-factor as its height or if it's out of the question and needs to be sovlved in another way?
