/**
 * This class returns base fonts for all component types on various OS.
 * This is some kind of workaround since there is no good way to retrieve native component fonts from OS itself.
 * Usually it is native L&F who setup system fonts but inside it simply has hardcoded fonts, which is not really different from my way.
