Adam Jackson 392da389d7 glx: Fix computation of GLX_X_RENDERABLE fbconfig attribute 
>From the GLX spec:

    "GLX_X_RENDERABLE is a boolean indicating whether X can be used to
    render into a drawable created with the GLXFBConfig. This attribute
    is True if the GLXFBConfig supports GLX windows and/or pixmaps."

Every backend was setting this to true unconditionally, and then the
core ignored that value and sent true unconditionally on its own. This
is broken for ARB_fbconfig_float and EXT_fbconfig_packed_float, which
only apply to pbuffers, which are not renderable from non-GLX APIs.

Instead compute GLX_X_RENDERABLE from the supported drawable types. The
dri backends were getting _that_ wrong too, so fix that as well.

This is not a functional change, as there are no mesa drivers that claim
to support __DRI_ATTRIB_{UNSIGNED_,}FLOAT_BIT yet.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:

        http://lists.freedesktop.org/mailman/listinfo/xorg

Please submit bug reports to the Xorg bugzilla:
