Comment (by kencu):

 I have found a method to override the loading of <OpenGL/glext.h> by
 tweaking the header in LegacySupport.

 It will always prevent the loading of <glext.h> if LegacySupport is
 enabled, but I'm thinking that this is in general a good thing, as all
 systems since 10.7 have had the headers this way, and it's likely
 everything expects that now (like mesa does).

 For older software -- well, it won't need LegacySupport, so it won't be
 affected, if it would have been affected, which is not likely.

 Once Ionic and I finish mucking around with legacysupport, I'll push this
 too.
