+/**
+ * @file
+ * Binding of the DRI interface (dri_interface.h) for DRISW.
+ *
+ * The DRISW structs are 'base classes' of the corresponding DRI1 / DRI2 (DRM)
+ * structs. The bindings for SW and DRM can be unified by making the DRM structs
+ * 'sub-classes' of the SW structs, either proper or with field re-ordering.
+ *
+ * The code can also be unified but that requires cluttering the common code
+ * with ifdef's and guarding with (__DRIscreen::fd >= 0) for DRM.
