A 1.0 release will not be made until the following drivers are available and solidly tested:
* GD
* Imagick
* Gmagick
* GmagickCLI
* Magick (unified driver that will use either ImageMagick or Gmagick automatically depending on what is available)
* MagickCliDriver (unified driver that can be configured to use either ImageMagick or Gmagick CLI tools)
