Since 8702c938b3 the pixmap formats are
handled in a single place. In the process of conversion the difference
between pixmap formats that can be uploaded and those that can be
rendered on GL side has been lost. This affects only 1-bit pixmaps: as
they aren't supported on GL, but can be converted to a R8 or A8 format
for rendering (see glamor_get_tex_format_type_from_pictformat()).
To work around this we add a separate flag that specifies whether the
format actually supports rendering in GL, convert all checks to use this
flag and then add 1-bit pixmap formats that don't support rendering in
GL.

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.
