Previously, when the backend doesn't implement root_change(), we will
deinit, and then init the backend again. However, we didn't free all the
images previously returned by the backend. There is no guarantee that
these images will be valid across deinit/init.
So, make sure they are freed.

Make sure before the mapping operation begins, the window is always in
UNUNMAPPED state. This makes it easier to reason about things, such as
resource availability, etc.

Previously we try to keep the image data until the rebind succeeds. This
way even if the rebind fails, we still have something to display.
But that triggers a NVIDIA driver bug. Basically you cannot have more
than one names (XIDs) of a window pixmap. NVIDIA driver doesn't like
that, and binding the pixmap with its aliases will fail. This can
sometimes happen if we name the new pixmap before freeing the old one during
rebind, and the pixmap doesn't actually change (i.e. the rebind is
unnecessary, could happen because of X event handling complications).

Clear the STALE_IMAGE flag set by win_update_bounding_shape to avoid an
unnecessary image data invalidation.
Mainly to workaround a NVIDIA bug. For more detailed explanation, see

Instead queue up configure notification while the window is unmapped,
just update the window geometry when the window is mapped.
Simplify the logic a little bit.

Use a flag to mark whether the image needs update, and only update once
per frame.
Also refactor some common code into functions, and handle image errors
properly.

Setting glx-swap-method to value other than "undefined" and "buffer-age"
could potentially cause rendering problems. So remove them, the meaning
of the remaining options can be more precisely captured by "use-damage",
so create a new option under that name.
--glx-swap-method is deprecated in favor of the new option --use-damage.

struct _glx_image_data needs to be freed even when refcount is not 0.
Also fixed a typo in glx_bind_pixmap.

Rectangle textures was used as a fallback when the driver doesn't
support non-power-of-two (NPOT) textures. Since we are using OpenGL 3.0 now,
which includes support for NPOT textures, we don't need this fallback
anymore.

blur_textures are not initialized when blur is disabled, but we still
try to resize them in gl_resize.
Don't do that.

Choose the best vsync method for the user, instead of asking them to
frustratingly try every one of the options to see what works.
With this commit, the `vsync` option will take only a boolean value.
