ffffgggglllluuuuEEEErrrrrrrroooorrrrSSSSttttrrrriiiinnnngggg produces an error string from an OpenGL or GLU error
code. The string is in an ISO Latin 1 format. For example,
ffffgggglllluuuuEEEErrrrrrrroooorrrrSSSSttttrrrriiiinnnngggg(GGGGLLLL____OOOOUUUUTTTT____OOOOFFFF____MMMMEEEEMMMMOOOORRRRYYYY) returns the string _o_u_t _o_f _m_e_m_o_r_y.
The standard GLU error codes are GGGGLLLLUUUU____IIIINNNNVVVVAAAALLLLIIIIDDDD____EEEENNNNUUUUMMMM, GGGGLLLLUUUU____IIIINNNNVVVVAAAALLLLIIIIDDDD____VVVVAAAALLLLUUUUEEEE, and
GGGGLLLLUUUU____OOOOUUUUTTTT____OOOOFFFF____MMMMEEEEMMMMOOOORRRRYYYY. Certain other GLU functions can return specialized
error codes through callbacks. Refer to the ggggllllGGGGeeeettttEEEErrrrrrrroooorrrr reference page
