[Piglit] [PATCH 5/5] glut_waffle: Add input support for X11
Chad Versace
chad.versace at linux.intel.com
Wed Aug 29 23:16:51 PDT 2012
Add support for input when using glut_waffle's GLX and
X11/EGL backends. Tested with fbo-clean-formats; I cycled through the
tests with the keyboard and then quit with the escape key.
