box-drawing: add infrastructure for rendering box drawing characters ourselves
...
* ‘term’ struct contains an array of 160 fcft glyph pointers
* the glyph pointers are lazily allocated when we need to draw a box
drawings character
* Filtering out box drawings characters is easy - they are (except
unicode 13, which isn’t handled yet )all in a single range.
