Image windows

Images loaded into the X Window version of imal can be placed in separate windows instead of the large main window by checking the ``Separate window'' box in the ``Load image'' dialog. With a few minor exceptions, images in separate windows have the same functionality (cut/paste, image math, densitometry, etc) as images on the main window. Cut/paste functions identically regardless of whether the source and destination are on the main window or on separate windows. Additionally, if the Window Manager permits, image windows can be created with or without a frame, depending on the settings in the ``Config'' dialog.

The advantages of separate windows are:

1. Entire image is visible without scrolling
2. Image can be iconified when not needed
3. Scroll bars can be added (using the menu in the upper left corner. This feature is only available in window managers that support it, such as fvwm.)
4. Images can be positioned anywhere on the screen

Disadvantages are:

1. Images cannot be superimposed, added, or subtracted without using ``image math'' function.
2. Transparency and chromakey do not work.
3. Composite images cannot be created.
