Linux: When calculating cell widths use the actual rendered bitmap width in addition to the horizontal advance reported by FreeType.
...
The horizontal advance is insufficient for some fonts at some point
sizes. So although rendering the characters is slower, we do it
to ensure cell width is correct. Fixes #352

Almost always resize glyphs that are too wide
...
When using FreeType, rescale glyphs that dont fit if they are more than
1px wider than the cell rather than 25% of the cell width. This matches
the behavior of CoreText and is needed for rendering the various Emoji
with default text presentation (i.e. emoji that have wcwidth() == 1)
