GLISENABLED()							 GLISENABLED()

NAME
       glIsEnabled - test whether a capability is enabled

C SPECIFICATION
       GLboolean glIsEnabled( GLenum cap )

PARAMETERS
       cap  Specifies a symbolic constant indicating a GL capability.

DESCRIPTION
       glIsEnabled returns GL_TRUE if cap is an enabled capability and returns
       GL_FALSE otherwise.  Initially all capabilities	except	GL_DITHER  are
       disabled; GL_DITHER is initially enabled.

       The following capabilities are accepted for cap:

NOTES
       If an error is generated, glIsEnabled returns 0.

       GON_OFFSET_LINE,	 GL_POLYGON_OFFSET_POINT,  GL_TEXTURE_COORD_ARRAY, and
       GL_VERTEX_ARRAY are only available if the GL version is 1.1 or greater

ERRORS
       GL_INVALID_ENUM is generated if cap is not an accepted value.

       GL_INVALID_OPERATION is generated if glIsEnabled	 is  executed  between
       the execution of glBegin and the corresponding execution of glEnd.
