r20272 Monday 14th January, 2013 at 22:02:06 UTC by Angelo Salese
Added a preliminary boolean flag to MC6845 interface structure: "show border area". If true, it will show the whole video area including border + blanking areas. [Angelo Salese]

Bulk replaced const mc6845_interface -> MC6845_INTERFACE, nw

(MESS)
SMC-777: enabled to show the border area in MC6845 interface, changed various video related function accordingly [Angelo Salese]
