Remarks This method creates a new empty image. If the new images is a 'true colour' (24bit) image
then the whole of the image is initialsed to black. If it is a palette image then the
first colour allocated with 'colourAlloc' function is deemed to be the background colour.
Where possible it is recommended that images use true-colour, which enables things like
anti-aliasing of text and shapes. Example
// Create a new image - 250 pixels wide, 100 tall using 24 bit colour
var myImage = new GraphicImage;
myImage.create(250,100);
