By the way, any size properties except may be linewidth are good to be
e.g. in mm or pt. This way theme naturally becomes HiDPI-ready, way
better than with GTK_SCALE, which needs to be integer due to its
conception of logical pixels. I noticed, that widget size never become
fractional, its extents are aligned to pixels.

I used pt for check/radio boxes, to match them to font size.
