Detailed Description

This is a message which identifies a particular raster element, and is used by two events:

• SWEVT_RR_ELEMENT_PENDING: Lets the cache instance know that a raster for the given id is on its way. This allows the cache to respond to queries which arrive before the raster data as if it was already there, thus preventing the redundant work of creating the raster twice.
• SWEVT_RR_ELEMENT_UNLOCK: Unlock a raster element. If no other locks apply, it is eligible for purging at the discretion of the cache implementation.
