v1

Brief

This is intended as the first release of the compton maintenance fork. Since compton is unlikely to get a major update in the future, we will use a simple version number system from now on: the version name will only contain a single number which is bumped every release.

Notable changes since last mainline update:

• You can now explicitly set the window opacity to 100 to make the window opaque. Previously doing this will make the window take the default opacity
• Fix a compatibility issue with Mesa 18 (chjj/compton#477)
• Merged several outstanding upstream pull request
• Various bug fixes.
