Non-CSO State
^^^^^^^^^^^^^
Every instance with instanceID in the range between ``start_instance`` and
``start_instance``+``instance_count``-1, inclusive, will be drawn.
-If there is an index buffer bound, and ``indexed`` field is true, all vertex
-indices will be looked up in the index buffer.
+If ``index_size`` != 0, all vertex indices will be looked up from the index
+buffer.
In indexed draw, ``min_index`` and ``max_index`` respectively provide a lower
and upper bound of the indices contained in the index buffer inside the range
