imageinterlace() turns the interlace bit on or off. If interlace is 1 the image will be interlaced, and if interlace is 0 the interlace bit is turned off.
If the interlace bit is set and the image is used as a JPEG image, the image is created as a progressive JPEG.
This function returns whether the interlace bit is set for the image.
