.LP
These functions set or get property values. All property values are expressed
in human-readable form. Boolean properties are expressed in case insensitive
form of "true" or "false". Properties that are represented by ASCII hexadecimal
contain no leading characters to indicate a base hexadecimal representation
(that is, no leading "0x"). The \fIprop\fR argument can be one of the following
values:
