Hi,
I'm working on a plug-in that needs to allow end-user to pick a color from colorpicker. Instead of attaching external libraries I would like to use color picker that is used for native APEX Color picker Item.
These files are:
I can generate URLs to CDN files but I would rather have behaviour similar to described in Application User Interface Details like on screen below:

Is there is a way I can achieve similar effect in the plug-in definition URL files to load or in the plug-in PL/SQL? I know there are APIs like apex_javascript.add_3rd_party_library_file and apex_css.add_3rd_party_library_file but these are described with comments:
--==============================================================================
-- Adds the script tag to load a 3rd party javascript library file (supported
-- libraries: jQuery, jQueryUI) and will also take into account the specified
-- Content Delivery Network for the application.
and the color picker is based on http://www.eyecon.ro/colorpicker/

/*
* The {@link apex.widget}.colorpicker allows to use a color picker dialog to pick a color.
* Internally uses the jQuery colorpicker plug-in http://www.eyecon.ro/colorpicker/
**/
Is there any way I can tell apex to load these files when the plug-in is used or should I extract files and attach them myself for the plug-in?
