glCullFace specifies whether front- or back-facing facets are culled (as specified by mode) when facet
       culling is enabled. Facet culling is initially disabled. To enable and disable facet culling, call the
       glEnable() and

       glDisable commands with the argument GL_CULL_FACE. Facets include triangles, quadrilaterals, polygons,
       and rectangles.

       glFrontFace() specifies which of the clockwise and counterclockwise facets are front-facing and
       back-facing. See glFrontFace().

GL_INVALID_ENUM is generated if mode is not an accepted value.

       glCullFace - specify whether front- or back-facing facets can be culled

       If mode is GL_FRONT_AND_BACK, no facets are drawn, but other primitives such as points and lines are
       drawn.

mode
           Specifies whether front- or back-facing facets are candidates for culling. Symbolic constants
           GL_FRONT, GL_BACK, and GL_FRONT_AND_BACK are accepted. The initial value is GL_BACK.
