My understanding is that we have objects which are "high-level"
constructs such as lines, axes, etc... The objects are reference by
their handle which is a unique identifier
Each of these objects has properties (i.e. lines have width, xdata, etc...)
so the "set(h,prop,val)" function sets the property "prop" of the
object refernced by the handle "h" to the value "val"
