//     Function: PNMTextMaker::set_interior_flag
//       Access: Published
//  Description: Sets the flag that indicates whether the interior of
//               hollow fonts is identified as a preprocess as each
//               glyph is loaded.  If this flag is true, you may
//               specify an interior color along with a fg and bg
//               color when you place text; if the flag is false, the
//               interior color is ignored.
//
//               It is generally best to set_native_antialias(0) when
//               using this feature.  Also, this works best when the
//               pixel size is not very small.
