* Check for inkscape, optipng, and sass in the PATH with configure
* Define themedirs once in configure instead of each Makefile
* Set GTK3_VERSION to compatible version instead of actual version
autotools doesn't like symlinks much, especially when building outside
of the source tree. This also adds better version detection errors.
* Don't distribute gulpfile.js as it has been removed
* Don't need $(srcdir) when defining EXTRA_DIST
Distributions are always prepared from the sources.
* Install theme index files using automake
* Generate and install XFWM4 files properly with autotools
This handles parallelism better and allows out-of-source builds.
* Generate and install GTK+2 files properly with autotools
This handles parallelism better and allows out-of-source builds.
* Generate and install GTK+3 files properly with autotools
This handles parallelism better and allows out-of-source builds.
