+ * Resolve buffers before entering a glBegin/glEnd block. This is
+ * necessary to prevent recursive calls to FLUSH_VERTICES.
+ *
+ * This resolves the depth buffer of each enabled depth texture and the HiZ
+ * buffer of the attached depth renderbuffer.
+ *
+ * Details
+ * -------
+ * When vertices are queued during a glBegin/glEnd block, those vertices must
+ * be drawn before any rendering state changes. To ensure this, Mesa calls
+ * FLUSH_VERTICES as a prehook to such state changes. Therefore,
+ * FLUSH_VERTICES itself cannot change rendering state without falling into a
+ * recursive trap.
+ *
+ * This precludes meta-ops, namely buffer resolves, from occurring while any
+ * vertices are queued. To prevent that situation, we resolve some buffers on
+ * entering a glBegin/glEnd
+ *
+ * \see brwCleanupExecEnd()
