Accent Support Progress

• [x] If there is no accent, typeset like normal.
• [x] Take largest accent smaller than nucleus.
• [x] Layout nucleus with style cramped.
• [x] Baseline of result == baseline of base.
• [x] Determine offset of accent:
  • Accent has attachment correction:
    • [x] If accentee has attachment correction, then align attachment corrections of both.
    • [x] Otherwise, align attachment correction of accentee with center of nucleus, plus italics correction of nucleus is a symbol.
  • Accent has no attachment correction:
    • [x] If accentee has attachment correction, center of accent with accent correction of base.
    • [x] Align accent center with base center (plus) italics correction if it's a symbol.
• [x] For superscripts, if accentee is simple symbol, scripts should not take accent into account for height. See #4.
• [ ] The width of the resulting box is the width of the base.
• [ ] BottomAccent: vertical placement is directly below nucleus, no correction takes place.
• [ ] WideAccent vs Accent: Don't expand non-WideAccent types by default.
• [ ] Implement FlattenedAccentBaseHeight.
