Log message:
  Don't try the accelerated glyphs path for component-alpha text (which
  I don't expect drivers to be able to accelerate without exa assistance).
  Instead, drop back to plain old miGlyphs for a 62.5% +/- 1.5% reduction
  in runtime of my ls -lR test (n=5) with component alpha.  While a
  reasonable approach would seem to be making a better test to see whether
  the entire path would be accelerated and force migration appropriately,
  my attempt at this made the situation much worse.
