Revision: 241 http://trac.macosforge.org/projects/xquartz/changeset/241 Author: gstaplin@apple.com Date: 2009-02-22 16:06:03 -0800 (Sun, 22 Feb 2009) Log Message: ----------- Correct the currentReadable usage with the apple_xgl_api_read.c code. The glCopyPixels may not be right in the case of a readable drawable specified to glXMakeContextCurrent. I think it needs more testing.
