glPolygonMode controls the interpretation of polygons for rasterization.  face describes which polygons
       mode applies to: both front and back-facing polygons (GL_FRONT_AND_BACK). The polygon mode affects only
       the final rasterization of polygons. In particular, a polygon's vertices are lit and the polygon is
       clipped and possibly culled before these modes are applied.

       Three modes are defined and can be specified in mode:

       GL_POINT
           Polygon vertices that are marked as the start of a boundary edge are drawn as points. Point
           attributes such as GL_POINT_SIZE and GL_POINT_SMOOTH control the rasterization of the points. Polygon
           rasterization attributes other than GL_POLYGON_MODE have no effect.

       GL_LINE
           Boundary edges of the polygon are drawn as line segments. Line attributes such as GL_LINE_WIDTH and
           GL_LINE_SMOOTH control the rasterization of the lines. Polygon rasterization attributes other than
           GL_POLYGON_MODE have no effect.

       GL_FILL
           The interior of the polygon is filled. Polygon attributes such as GL_POLYGON_SMOOTH control the
           rasterization of the polygon.

GL_INVALID_ENUM is generated if either face or mode is not an accepted value.

       To draw a surface with outlined polygons, call

           glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);

       glPolygonMode - select a polygon rasterization mode

       Vertices are marked as boundary or nonboundary with an edge flag. Edge flags are generated internally by
       the GL when it decomposes triangle stips and fans.

face
           Specifies the polygons that mode applies to. Must be GL_FRONT_AND_BACK for front- and back-facing
           polygons.

       mode
           Specifies how polygons will be rasterized. Accepted values are GL_POINT, GL_LINE, and GL_FILL. The
           initial value is GL_FILL for both front- and back-facing polygons.
