6ce5e3d34a optimizer repair related to use-before-defined 
Don't optimize away a use-before-definition in an early compiler
pass. (More specifically, adjust the meaning of a flag within an
optimization helper function so that it works for decisions before the
letrec-fixing pass.)

Uses of mzlib/class100 have already been removed. The library's
removal was promised in the release notes for Racket v5.3.2.

f8813474d4 adjust drracket frame startup to conform to new checks 
I don't think that there was a bug behind this change. There may
have been and it is probably now easier to reason about this code
than it was before, but I think that this code was probably using
object?, not checking directly with undefined) properly.

800641e11a racket/draw Cocoa: hack to make Courier New work in 10.{7,8} 
The bounding box in the Courier New font is wrong in Mac OS X
10.7 and 10.8. Recognize that combination and make the bounding
box bigger as a workaround.

69984fb231 racket/gui Cocoa: repairs for Cairo and Pango 
* Fix a clipped-rendering problem for text in Cairo.

 * Fix Pango's CoreText back-end to support non-BMP characters.

   Note that Emoji characters still do not render. Cairo uses
   CGContextShowGlyphsWithAdvances() to draw glyphs, but it
   would need to use CTFontDrawGlyphs() to make Emoji work.
   (Mozilla has a patch to do that for some older version
   of Cairo, so look there if it seems worth doing one day.)

 * Disable Pango's CoreText font fallbacks in favor of the
   Racket-implemented fallback.

   This is not obviously a good idea, but it restore the
   `racket/draw` hack of prefering "Arial Unicode MS". Otherwise,
   various symbol glyphs are chosen badly, such as #\u273A,
   at least on my machine.

 * Drop the clusters argument to `pango_cairo_show_glyph_string`,
   which turns out to be unnecessary.
