Subject: [PATCH] glx: Don't strip off window/pixmap support from float
 fbconfigs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The X server doesn't get this wrong. It's not the client's job to
correct what the server says here. And if anyone ever implements HDR for
X11, you might in fact want to be able to use floats with a window.
