Steps for creating transparent (alpha) textures in Gimp 2.6
        One: Started off with a simple flat (no layers or alpha) image... 200 X 150, white background.
        Two: Added a beautiful black swirl thingy to my basic image...
        Three: Clicked on the Fuzzy Select tool (on top row, 4th from the left (magic wand)).
        Four: Right clicked in the Layer area (image here shows the top of it) and selected "Add Alpha Channel".
        Five: Clicked on the white background in my image and hit the delete key (on the keyboard) and gimp shows me the checkerboard (meaning transparent) background. I see white edges around my swirl thingy... didn't want that.
        Six: I used CTRL + Z (to undo), and clicked "Select" - "Grow..." and used a value of 1... then I clicked "Select" - "Feather..." and used a value of 1 again. While still selected I hit delete again and the beautiful swirl thingy had no white edges.
        Seven: This image shows the how the swirl thingy appears in gimp without anything selected.
        Here is the finished image, this page was intentionally made slightly blue in hopes of showing the transparency better. This image is not very smooth looking because I worked with it at this size, typically I would work on the image at least double the size, then once finished scale it to the size I want.
