+ * FIXME: it is unclear if primitives_storage_needed (which is generally
+ * the same as pipe query num_primitives_generated) should increase
+ * if SO is disabled for d3d10, but for GL we definitely need to
+ * increase num_primitives_generated and this is only called for active
+ * SO. If it must not increase for d3d10 need to disambiguate the counters
+ * in the driver and do some work for getting correct values, if it should
+ * increase too should call this from outside streamout code.
