The netsurf core is driven from numerous operation tables most of which are now set through a common netsurf_register() interface. The font and plotting interfaces are currently separate and unlike all the other operation tables are modified for differing contexts. This change moves the font operations alongside all the other operations table and remove unnecessary interaction with the renderers font internals. Further this also removes the need for css internals to be visible in frontends.
