No changes to the transition manager are needed since
nsTransitionManager::StyleContextChanged already makes the appropriate
calls to ConsiderStartingTransition for 'all', and that existing code
should work fine within a loop (just like the existing code to handle
shorthands or other property duplication works).
This adds entries for property aliases as though they are shorthands.
This fits with the CSS working group's recent resolution to describe
aliases as shorthands, recorded in
http://lists.w3.org/Archives/Public/www-style/2012Aug/0770.html .
The property_database.js entries themselves are copied from the
non-alias entries for the properties, with these changes:
(1) The property name is changed to the prefixed form
(2) The domProp entry is changed to the prefixed form
(3) Adding alias_for entries for each property.
(4) When type is CSS_TYPE_LONGHAND in the target of the alias, type for
the alias is CSS_TYPE_SHORTHAND_AND_LONGHAND and a subproperties
entry is added with the target of the alias.
There are also some indentation fixes to the copied entries in
property_database.js (made before they were copied, and thus affecting
the original as well).
