Detailed Description

ImageView extension to give information about how to efficiently access it in a multi-threaded environment.

ImageView content can be accessed with following features:

• thread-safe: no race conditions when accessing with multiple threads
• parallel-access by tile: hints benefits when tiles are accessed in parallel
• parallel-access: hints benefits when regions are accessed in parallel

In any case, parallel reading and writing into the same part of an image is not advised, as there is no control over the ordering of operations.
