/**
|
|
* This structure represents a directional range of the content. It is defined
|
|
* by two points in the content, where each one is defined by an accessible
|
|
* object and an offset relative to it. A typical case of a range point is
|
|
* a text accessible and text offset within it.
|
|
*
|
|
* The "anchor" is one point of the range and typically remains constant.
|
|
* The other point is the "active" point, which typically corresponds to
|
|
* the user's focus or point of interest. The user moves the active point to
|
|
* expand or collapse the range. In most cases, anchor is the start of the range
|
|
* and active is the end. However, in case of selection, when selecting
|
|
* backwards (e.g. pressing shift+left arrow in a text field), the start of
|
|
* the range is the active point, as the user moves this to manipulate
|
|
* the selection.
