/**
* @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.
