+ * EXTENSION SUPPORT
+ *
+ * As the driver supports a range of Mesa versions it can be the case that it
+ * needs to support different extensions and extension versions depending on
+ * the version of Mesa that it's built against. As a guide the following rules
+ * should be followed:
+ *
+ * 1) If an extension appears in some supported versions of Mesa but not others
+ * then it should be protected by the extension define, e.g.:
+ * #if defined(__DRI_IMAGE)
+ * <code>
+ * #endif
+ *
+ * However, if it appears in all versions then there's no need for it to
+ * be protected.
+ *
+ * 2) Each driver supported extension should have a define for the maximum
+ * version supported by the driver. This should be used when initialising
+ * the corresponding extension structure. The Mesa extension version define
+ * should *NOT* be used.
+ *
+ * 3) If the driver supports a range of versions for a given extension then
+ * it should protect the extension code based on the Mesa extension version
+ * define. For example, if the driver has to support versions 7 to 8 of the
+ * __DRI_IMAGE extension then any fields, in the __DRIimageExtension
+ * structure, that appear in version 8 but not 7 should be protected as
+ * follows:
+ * #if (__DRI_IMAGE_VERSION >= 8)
+ * .createImageFromDmaBufs = PVRDRICreateImageFromDmaBufs,
+ * #endif
+ *
+ * Obviously any other associated code should also be protected in the same
+ * way.
