glIsProgram returns GL_TRUE if program is the name of a program object previously created with
       glCreateProgram() and not yet deleted with glDeleteProgram(). If program is zero or a non-zero value that
       is not the name of a program object, or if an error occurs, glIsProgram returns GL_FALSE.

       glIsProgram - Determines if a name corresponds to a program object

       No error is generated if program is not a valid program object name.

       A program object marked for deletion with glDeleteProgram() but still in use as part of current rendering
       state is still considered a program object and glIsProgram will return GL_TRUE.

           Specifies a potential program object.
