DESCRIPTION
GLparamname is the name of a GL hardware configuration parameter as

GD_ prefix, and in upper or lower case. The returned value is the result
of interpreting the string as a symbolic constant and passing it to the
function getgdesc() .
If more than one parameter name is given, a corresponding list of
parameter values is returned. If no parameter names are given, a list of
all known parameter names and corresponding parameter values is returned.
If the optional argument -screen screennum is given, the parameters for
the given screen are returned. By default, the parameters of the current
GL screen are returned.
