#15648: switch_theme action hook may provide the old template value

     Type:  feature request  |      Status:  new                                   
 Priority:  normal           |   Milestone:  Awaiting Review                       
Component:  Themes           |     Version:                                        
 Severity:  trivial          |    Keywords:  theme, switch, custom header, defaults
-----------------------------+----------------------------------------------
 When someone change its theme, and both support custom header, then the
 banner and the text color are not preserved (these options are theme
 specific)


 Anyway, one may want to preserve these values :
  * check if the new theme has its default value
  * check if the old theme values are compatible
  * ...
  * migrate the values

 But in order to do this, WordPress should provide the value of the old
 theme in use. It would be easy to get it in switch_theme() and to send it
 as a second argument to the action hook.
