+ *
+ * On Gen6, the size of transform feedback data is limited not by the number

+ * entry per matrix column. Since the only way we can communicate our

+ * MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS, we need to plan for the
+ * worst case, in which all the varyings are floats, so we use up one binding
+ * table entry per component. Therefore we need to set aside at least 64
+ * binding table entries for use by transform feedback.
+ *
+ * Note: since we don't currently pack varyings, it is currently impossible
+ * for the client to actually use up all of these binding table entries--if
+ * all of their varyings were floats, they would run out of varying slots and
+ * fail to link. But that's a bug, so it seems prudent to go ahead and
+ * allocate the number of binding table entries we will need once the bug is
