Scale down an image to fit a particular size and save a new copy of the image.
The PNG transparency will be preserved using the function, as well as the
image type. If the file going in is PNG, then the resized image is going to
be PNG. The only supported image types are PNG, GIF, and JPEG.
Some functionality requires API to exist, so some PHP version may lose out
support. This is not the fault of WordPress (where functionality is
downgraded, not actual defects), but of your PHP version.
