* Add PushBrightness to surface
* Highlight selectable objects
Check if mapentity is selectable. (seems reasonable)
Request objects to highlight themselves is required (idk)
* String2enum ObjectAnimationMode
* Render objects at their assigned layer
Gets the orderflag from the object record and assign it to the mapentity
so the renderer can get at it.
This adds another render pass that loops through the objects.
* Get object animation speed from their txt entry
* Use integer directions for rotating map entities
* Manage composite directly in npc
* Player manages its own composite
* Split up animation mode types
Players, monsters, objects all have their own types
* Clean up AnimatedEntity
* Rename AnimatedEntity -> Object
* Keep the object txt record on hand in Object
