 /**
- * Draw vertex arrays, with optional indexing.
- * Basically, map the vertex buffers (and drawing surfaces), then hand off
- * the drawing to the 'draw' module.
+ * This function handles drawing indexed and non-indexed prims,
+ * instanced and non-instanced drawing, with or without min/max element
+ * indexes.
+ * All the other drawing functions are expressed in terms of this
+ * function.
+ *
+ * For non-indexed prims, indexBuffer should be NULL.
+ * For non-instanced drawing, instanceCount should be 1.
+ * When the min/max element indexes aren't known, minIndex should be 0
+ * and maxIndex should be ~0.
