Skinning

Objectives

Enable internal designers to more easily customize the look of Second Life
Enable external developers and residents to save customizations and prepare skin "packages"

Create 'templates.xml' file with default attributes for each widget type

Other templates for common attribute sets can also be declared here
Widgets can declare a tempate (default to the default one)
All default values will be removed from the code
Create a tool to process all existim .xui files and write out only the non default values

Separate pre-cached images with asset ids from UI images

Replace any art embedded in code
- Including programatic art with attributes, e.g. volume sliders
- Remove any backgrounds from icons, etc (use alpha)
- Ensure that all images can be cropped and scaled
- Allow specification of fized size borders (i.e. so that button graphics with narrow boarders scale correctly)
Enable additional attributes for colors, etc

Enable reloading of all floaters including the menus and overlay bar
Ensure all floaters can handle missing UI elements and will behave reasonably or refuse to open with an appropriate message
Create a global floater/panel map and have floaters/panels to specify their type (e.g. "floater_inventory" -> LLFloaterInventory) in XML
Allow buttons to open floaters by name
- Include support for opening a specific tab
- Differentiate between toggling state of singletons, showing/focusing, and opening new instances
Allow menus to be expanded/collapsed for simple/advanced usage

Allow residents to save changes to the UI and preserve them across updates
Allow residents to package changes and easily distribute them for easy installation by other users
Include the ability to show/restore the original skin

Make iconic panels (i.e.. build tools) generally available
- Combination of fully iconic buttons and the ability for a button to open a specific tab in a floater
