Beware that in the latest revision of the development version, the syntax of
the Image constructor has changed.
Before, it was:
New Image(Width As Integer, Height As Integer, Optional Transparent As
Now, Image are always transparent, and the syntax is:
New Image(Optional Width As Integer, Optional Height As Integer, Optional
Format As Integer, Optional Color As Integer)
Format can be Image.Standard, or Image.Premultiplied, the latest meaning than
the color components are premultiplied by the alpha component.
Color is a color that will be used to initialize the image contents.
Otherwise, the contents is undefined.
