Revision: 262 http://trac.macosforge.org/projects/xquartz/changeset/262 Author: gstaplin@apple.com Date: 2009-02-25 23:49:45 -0800 (Wed, 25 Feb 2009) Log Message: ----------- Test if the drawable is the current drawable in a safer way. Before if the context was new and glXSwapBuffers was called without a drawable made current, it would likely crash while dereferencing NULL. We want it to generate a nice XError instead.
