-Wextra is removed, some of the warning flags included in -Wextra are
now explicitly set.
-Wno-unused-parameter is removed. The warnings will take a while to fix.

Doing this forces compton to blur every windows' background.
However, doing this can be beneficial, we will figure out a way
to do this properly in the future.

Previously, only the WM windows (window manager usually reparents the
application windows under its own window so it can manage them) are
checked for alpha channels. Some of the window managers (e.g. awesome)
acquire alpha channels for all of the WM windows, whether the underlying
application windows have alpha channel or not.
With this change, the application windows are also checked for alpha
channels. If a WM window has alpha but its child doesn't, only the WM
frame will be considered to be semi-transparent. Thus preventing some
unnecessary blurring.

During normalization of the kernel, the center element is added to the
sum twice, causing the resulting elements to be smaller than they should
be.

This is done by extending the blur area internally when process
blurring.
Ping: #50, cause this fixes that problem but only when using the
experiemental backends.

When enabled, the result will be redirected to a window, and compton
won't take over the screen.
Makes debugging easier.

This will use --bindir value to install additional scripts into the same location
as compton binary (current behavior: hardcoded $prefix/bin).
Useful for custom installations and/or cross-compiling.
If screen is not redirected, we don't need to reinitialize the backend
when we got a root change event.
Fixes#189

To prepare for different blur methods, the blur interface of backends
has been splitted into two parts.
Now to use blur, a blur context must be created first; then, the blur
method should be called with the blur context created.
Updated the existing backends to the new interface. Also implemented
handling of the new blur options.

Also fill the center of parsed kernel with 1. This shouldn't change the
behavior of the old backends since they will modify the center of the
kernels.
