Font size

[Sarthak Kalani]

For some component value names, would be good to have a smaller font option. Though there is an option of changing width, (2,4,6 etc.), the granularity is too coarse. Font size 2 is not properly readable, while font 4 seems too big for smaller components. (Would like to have atleast 2, 2.5, 3, 3.5, 4 options, if not finer.)

Fonts can now be chosen using a dialog that draws on fonts provided by the OS. I'm marking this as resolved.
