Create Common nn::ui2d file structure page.

New page

nn::font and nn::ui2d share similar file structures. Some are used in nn::font [[Bffnt]] as well as nn::ui2d [[Bflyt]] and [[Bflan]]. This style of file may be a holdover from the 32-bit era, as newer ui2d formats like [[Bnvg]] have an [[Common nn::util|nn::util style]].
