I am developing a Dashboard widget, and would like to reduce its size by removing
elements within it (my priority are the "info" button graphics) and using the images
Apple provides in /System/Library/WidgetResources.

I also want to make my widget compatible with all versions of Mac OS X. I know that,
beginning with Mac OS X v.10.4.3 and higher, Apple began including Apple Classes in
OS X to simplify widget development. Upon examining the WidgetResources directory,
I've located the info button graphics in the folder "ibutton." Unfortunately, I am not sure
if this directory is included in OS X 10.4.0-10.4.2. I do not want to put my user in a
position when he/she finds that the info button is broken, and I do not want to raise my
widget's requirements.

If you are using Mac OS X 10.4.0-10.4.2, and have not applied the 10.4.3 update or any
further updates, please let me know if the "ibutton" directory exists in /System/Library/WidgetResources. If it does, it should contain four PNG graphics for
the buttons. Any assistance would be greatly appreciated. Thank you.
