Creating transparent images instead of using borders to make up the extra space (zc=2)

[GoogleCodeExporter]

I used the following modified code from around line 167 to set the black 
background (borders) to be transparent instead.

    // Restore transparency blending
    imagesavealpha ($canvas, true);

    // Set transparency on background color
    imagecolortransparent($canvas, $color);

Then I forced imagepng instead of imagejpeg to ensure transparency would be 
saved in the show_image function.

This creates large image sizes. I used to do this but got lots of complaints 
about it. I have now added a parameter for changing the colour of the 
background which should help a lot.
