Redlining

There are three main steps involved in redlining:

1. Pass the digitized coordinates from the client to the server.
2. Create a temporary feature source. This will be used to draw the lines on.
3. Create a layer to display that temporary feature source.

For example, see task_pane_redlining.php in the digitizing_features directory in the Developer Guide samples.
