Provide the way for theme developers to set the row height in SCM history view
It's not correct to rely on the row height 20px set in source:branches/1.3-stable/public/stylesheets/application.css#L165, cause, for example on my system (using Gnome/Linux) only checkbox takes 15px, plus cell padding etc. yields 26px total row height.
It'll be very good if we give theme authors the way to pass their settings in the
branchGraph function. The 20px value for
theme.js, but I consider it is the wrong way.
BTW. I think the script
window.onload assignment instead of adding load listener...
