sub gimprc_query {

Queries the gimprc file parser for information on a specified token.
BLURB

    $help = <<'HELP';
This procedure is used to locate additional information contained in the gimprc
file considered extraneous to the operation of the GIMP. Plug-ins that need
configuration information can expect it will be stored in the user gimprc
file and can use this procedure to retrieve it. This query procedure will
return the value associated with the specified token. This corresponds _only_
to entries with the format: (<token> <value>). The value must be a string.
Entries not corresponding to this format will cause warnings to be issued on
gimprc parsing and will not be queryable.

This procedure is used to add or change additional information in the gimprc
file that is considered extraneous to the operation of the GIMP. Plug-ins that
need configuration information can use this function to store it, and
gimp_gimprc_query to retrieve it.  This will accept _only_ parameters in the
format of (<token> <value>), where <token> and <value> must be strings. Entries
not corresponding to this format will be eaten and no action will be performed.

Returns the resolution of the monitor in pixels/inch. This value
is taken from the Preferences (or the windowing system if this is set in
the Preferences) and there's no guarantee for the value to be reasonable.
