We adjust 'end' to fit into _MaxElement, but that may result into a 'start'
value bigger than 'end' being passed downstream, causing havoc.
This could be seen with arb_robustness_draw-vbo-bounds, due to an
application bug.
/* Set 'end' to the max possible legal value */
assert(ctx->Array.ArrayObj->_MaxElement >= 1);
end = ctx->Array.ArrayObj->_MaxElement - 1;
