GIMP plugin to read/write GRA files

This is a simple plugin to allow GIMP to read and write .GRA image files as created by Terry Davis in his operating system TempleOS.

Installation

Install libgimp2.0 to be able to build it. On ubuntu you can type sudo apt-get install libgimp2.0-dev to get this.
Get the source from here (clone or whatever)
Enter the directory in terminal, type make and then make install. This will install the plugin binary in ~/.gimp-2.8/plugins/ and a palette file in ~/.gimp-2.8/palettes/.

To open .GRA files, just open them like you would any image file (File->Open). This only works with regular .GRA files (you will have to decompress any .GRA.Z files first).
To export an image as a .GRA file, simply make sure the file has a .GRA extension. .GRA files are indexed images using a fixed palette of 16-colors. If your image is not in this format you will be prompted before exporting the image. Clicking "Export" at this dialog will automatically convert the image.
