Almost always resize glyphs that are too wide

Browse Source 
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)
