Description
Packit Service 963350 
A value mapping object that attaches control sources to gobject properties. It
Packit Service 963350 
will map the control values directly to the target property range. If a
Packit Service 963350 
non-absolute direct control binding is used, the value range [0.0 ... 1.0]
Packit Service 963350 
is mapped to full target property range, and all values outside the range
Packit Service 963350 
will be clipped. An absolute control binding will not do any value
Packit Service 963350 
transformations.
