Detailed Description

Editor action classes.

Some important points:

• This is a polymorphic hierarchy of classes, so actions are usually passed around as editor_action pointers
• The pointers can, in general, be null. Always check for null before doing anything. The helper functions perform_ that take a pointer do that.
• The perform() functions can throw when an error occurs. Use smart pointers if you need to ensure the pointer is deleted.
