fcf4936592 improved error messages when handlers fail check-with tests 2011-09-01 18:27:25 -04:00

1f02106318 2htdp/image 
normalize the internal representation of bitmaps so it always uses an alpha
bitmap instead of sometimes using a mask bitmap and sometimes using alpha.
This also fixes a bug where the library would get consfused when it saved
a bitmap to a file, since it didn't record if it was an alpha bitmap or not.

This improves the save files that contain images, cutting the size for bitmaps
in half (bringing the drracket save file down to a mere 25x larger than the
png file format for the example I was using...)

This reverts commit 5c95e8d46d which was accidentally committed.

de9aec3051 Allowing paths in big-bang's record? argument and adjusting a test to make use of that feature. It would also be good to allow bitmap to take paths, but that is non-trivial, because of its assumption that non-literal strings are module paths 2011-07-02 20:13:39 -07:00

a3d00a910a More LGPL permissions from Chongkai, Neil, and Olin. 
Also, removed the LGPL blurbs from srfi/1, and redirect to the Racket
license.  (To avoid possible future issues with license changes, such as
LGPL version.)
