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.

Implement image processing in gl_compose using a frag shader.
gl_image_op is used to set flags corresponds to what processing is
needed for a texture.
Also implement proper reference counting for textures.

We only ever invert color of or dim the entire image, so just remove the
ability to do region based inversion and dimming. Making implementing
image_op easier.

This is basically just adapting old code to the new interface. A lot
of the functions are still stubs, but the basic stuffs is working.
What remains to be done:
* Implement gl_image_op. (It should do the operation lazily, only update
the flags on the texture. Actual processing will be delayed until composition.)
* Implement gl_copy. Now it just return the same image after incrementing the
refcount. It should actually copy the image data structure so it can have a
separate set of flags.

Because when the screen is unredirected, the window resource would have
already been freed. Fix a NULL pointer deref.

If monitor-repaint is not implemented by the backend, compton will
crash. This commit fix the crash by not doing monitor-repaint in that
case.

Rational: current workaround for Composite < 0.2 doesn't work with the
GLX backend, it also doesn't handle window border properly. Plus,
Composite 0.2 came out more than a decade ago, it's safe to assume
everyone has it.

Also remove xrender's prepare since it overwrite part of the screen

Pass the visible region of the image to the backend, so the backend
could optimize based on that information.

Handle backend initialization failure.
Also actually disable vsync when it's not supported in the new xrender
backend.
