+
+The XA state tracker is intended as a versioned interface to gallium for
+xorg driver writers. Initially it's mostly based on Zack Rusin's
+composite / video work for the Xorg state tracker.
+
+The motivation behind this state tracker is that the Xorg state tracker has
+a number of interfaces to work with:
+
+1) The Xorg sdk (versioned)
+2) Gallium3D (not versioned)
+3) KMS modesetting (versioned)
+4) Driver-private (hopefully versioned)
+
+Since Gallium3D is not versioned, the Xorg state tracker needs to be compiled
+with Gallium, but it's really beneficial to be able to compile xorg drivers
+standalone.
+
+Therefore the xa state tracker is intended to supply the following
+functionality:
+
+1) Versioning.
+2) Surface functionality (creation and copying for a basic dri2 implementation)
+3) YUV blits for textured Xv.
+4) Solid fills without ROP functionality.
+5) Copies with format conversion and - reinterpretation but without ROP
+6) Xrender- type compositing for general acceleration.
+
+
+The first user will be the vmwgfx xorg driver. When there are more users,
+we need to be able to load the appropriate gallium pipe driver, and we
+should investigate sharing the loadig mechanism with the EGL state tracker.
+
+IMPORTANT:
+Version compatibilities:
+While this library remains OUTSIDE any mesa release branch,
+and the major version number is still 0. Any minor bump should be viewed as
+an incompatibility event, and any user of this library should test for that
+and refuse to use the library if minor versions differ.
+As soon as the library enters a mesa release branch, if not earlier, major
+will be bumped to 1, and normal incompatibility rules (major bump)
+will be followed.
+It is allowed to add function interfaces while only bumping minor. Any
+user that uses these function interfaces must therefore use lazy symbol
+lookups and test minor for compatibility before using such a function.
