98b91a11e4 faster path for TCP input 
Avoid polling a file descriptor to determine whether it has bytes;
just try to read, and then go to epoll/kevent mode when available,
skipping a poll/select.

97da48ab67 remove/adjust obsolete C preprocessor cases 
Mac OS Classic and Palm ae long since unsupported.

TCP support implies sockets (since old Mac TCP is gone).

For what it's worth, make the build work without TCP support, although
no one ever builds that way.

58e8ed7d7d games/cards: add @2x card images 
For both original and @2x, adjust images to use alphas for the corner,
instead of drawing with clipping, which avoids alignment problems on
an @2x display.

54e42664df racket/draw: faster (on some platforms) path for drawing a bitmap 
The faster path applies in the common case of drawing a whole
bitmap, as opposed to a section of the bitmap.

Thanks to Laurent Orseau for tracking down this performance issue.

d1525edf62 Scribble search, etc.: fix URL decoding 
Use Javascript's decodeURIComponent() instead of unescape().

This repair makes searching for Unicode characters work from DrRacket
(e.g., via F1).

95cdd6e619 fix a performance bug in drracket's REPL IO. 
This one of those classic n^2-loop-that-should-be-linear bug. The fix
speeds up this program (when run in DrRacket) by about 1.75x:

  (for ([x (in-range 10000)])
    (display "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz\n"))

The bug is fairly old too: I introduced this bug on March 6th,
2004. (Thanks, Sam, for making that old history accessible!)
