Subject: [PATCH] Add API for checking ownership of region by position/entity
|
|
|
|
This may be useful for plugins which want to perform operations
|
|
over large areas outside of the buffer zone provided by the
|
|
regionaliser, as it is not guaranteed that anything outside
|
|
of the buffer zone is owned. Then, the plugins may use
|
|
the schedulers depending on the result of the ownership
|
|
check.
