/** Image/createImage
*
* SYNOPSIS
*   long createImage(widget, x, y, image)
* DESCRIPTION
*   This creates an image on your widget at x, y. The filename should be
*   given as the path parameter. In theory the image could be local or could
*   be a url. It works just like adding an image in your theme file. You
*   will need to save the return value to be able to call other functions on
*   your image, such as moveImage()
* ARGUMENTS
*   * long widget -- karamba
*   * long x -- x coordinate
*   * long y -- y coordinate
*   * string image -- image for the imagelabel
* RETURN VALUE
*   Pointer to new image meter

/** Image/getThemeImage
*
* SYNOPSIS
*   long getThemeImage(widget, name)
* DESCRIPTION
*   You can reference an image in your python code that was created in the
*   .theme file. Basically, you just add a NAME= value to the IMAGE line in
*   the .theme file. Then if you want to use that object, instead of calling
*   createImage, you can call this function.
*
*   The name you pass to the function is the same one that you gave it for
*   the NAME= parameter in the .theme file.

* DESCRIPTION
*   Changes the "intensity" of the image, which is similar to it's

*   determines how much to brighten or darken the image. Millisec specifies
*   how long in milliseconds before the image is restored to it's original
*   form. This is useful for "mouse over" type animations. Using 0 for
*   millisec disables this feature and leaves the image permanently
*   affected.
