+How to add a new post-processing filter
+=======================================
+
+The Gallium post-processing queue works by passing the current screen to a fragment shader.
+These shaders may be written in any supported language, but are added here in TGSI text
+assembly.
+
+You can translate GLSL/ARB fairly easily via llvmpipe (LP_DEBUG=tgsi). I don't know the
+status of the D3D state tracker, but if/when that works, I'd assume HLSL would be possible
+too.
+
+
+
+Steps
+=====
+
+1. Add it to PP
+2. Make it known to PP
+3. Make it known to driconf
+4. ????
+5. Profit
+
+
+
+
+1. Add it to PP
+---------------
+
+Once you have the shader(s) in TGSI asm, put them to static const char arrays in a header
+file (see pp_colors.h).
+
+Add the filter's prototypes (main and init functions) to postprocess.h. This is mostly a
+copy-paste job with only changing the name.
+
+Then create a file containing empty main and init functions, named as you specified above.
+See pp_colors.c for an example.
+
+
+
+2. Make it known to PP
+----------------------
+
+Add your filter to filters.h, in a correct place. Placement is important, AA should usually
+be the last effect in the queue for example.
+
+Name is the config option your filter will be enabled by, both in driconf and as an env var.
+
+Inner temp means an intermediate framebuffer you may use in your filter to store
+results between passes. If you have a single-pass filter, request 0 of those.
+
+Shaders is the number of shaders your filter needs. The minimum is 2.
+
+
+You could also write the init and main functions now. If your filter is single-pass without
+a vertex shader and any other input than the main screen, you can use pp_nocolor as your
+main function as is.
+
+
+
+3. Make it known to driconf
+---------------------------
+
+First time outside of auxiliary/postprocess. First, add a suitable description to
+drivers/dri/common/xmlpool/t_options.h, and regenerate options.h by running make in that
+directory. Use the name you put into filters.h as the config option name.
+
+With driconf aware of the option, make Gallium aware of it too. Add it to
+state_trackers/dri/common/dri_screen.c in a proper section, specifying its default value and
+the accepted range (if applicable).
+
+Do check that __driNConfigOptions is still correct after the addition.
+
+
+
+4. ????
+-------
+
+Testing, praying, hookers, blow, sacrificial lambs...
+
+
+
+5. Profit
+---------
+
+Assuming you got here, sharing is caring. Send your filter to mesa-dev.
+

+	 *
+	 * However (and this is not mentioned in the documentation), apparently
+	 * the macro version is _NOT_ a full superset of the normal version.
+	 * In particular, the macro version does not always work when relative
+	 * addressing is used in the source operands.
+	 *
+	 * This limitation caused incorrect rendering in Sauerbraten's OpenGL
+	 * assembly shader path when using medium quality animations
+	 * (i.e. animations with matrix blending instead of quaternion blending).
+	 *
+	 * Unfortunately, I (nha) have been unable to extract a Piglit regression
+	 * test for this issue - for some reason, it is possible to have vertex
+	 * programs whose prefix is *exactly* the same as the prefix of the
+	 * offending program in Sauerbraten up to the offending instruction
+	 * without causing any trouble.
+	 *
+	 * Bottom line: Only use the macro version only when really necessary;
+	 * according to AMD docs, this should improve performance by one clock

+ * \file ir_function_detect_recursion.cpp
+ * Determine whether a shader contains static recursion.
+ *
+ * Consider the (possibly disjoint) graph of function calls in a shader.  If a
+ * program contains recursion, this graph will contain a cycle.  If a function
+ * is part of a cycle, it will have a caller and it will have a callee (it
+ * calls another function).
+ *
+ * To detect recursion, the function call graph is constructed.  The graph is
+ * repeatedly reduced by removing any function that either has no callees
+ * (leaf functions) or has no caller.  Eventually the only functions that
+ * remain will be the functions in the cycles.
+ *
+ * The GLSL spec is a bit wishy-washy about recursion.
+ *
+ * From page 39 (page 45 of the PDF) of the GLSL 1.10 spec:
+ *
+ *     "Behavior is undefined if recursion is used. Recursion means having any
+ *     function appearing more than once at any one time in the run-time stack
+ *     of function calls. That is, a function may not call itself either
+ *     directly or indirectly. Compilers may give diagnostic messages when
+ *     this is detectable at compile time, but not all such cases can be
+ *     detected at compile time."
+ *
+ * From page 79 (page 85 of the PDF):
+ *
+ *     "22) Should recursion be supported?
+ *
+ *      DISCUSSION: Probably not necessary, but another example of limiting
+ *      the language based on how it would directly map to hardware. One
+ *      thought is that recursion would benefit ray tracing shaders. On the
+ *      other hand, many recursion operations can also be implemented with the
+ *      user managing the recursion through arrays. RenderMan doesn't support
+ *      recursion. This could be added at a later date, if it proved to be
+ *      necessary.
+ *
+ *      RESOLVED on September 10, 2002: Implementations are not required to
+ *      support recursion.
+ *
+ *      CLOSED on September 10, 2002."
+ *
+ * From page 79 (page 85 of the PDF):
+ *
+ *     "56) Is it an error for an implementation to support recursion if the
+ *     specification says recursion is not supported?
+ *
+ *     ADDED on September 10, 2002.
+ *
+ *     DISCUSSION: This issues is related to Issue (22). If we say that
+ *     recursion (or some other piece of functionality) is not supported, is
+ *     it an error for an implementation to support it? Perhaps the
+ *     specification should remain silent on these kind of things so that they
+ *     could be gracefully added later as an extension or as part of the
+ *     standard.
+ *
+ *     RESOLUTION: Languages, in general, have programs that are not
+ *     well-formed in ways a compiler cannot detect. Portability is only
+ *     ensured for well-formed programs. Detecting recursion is an example of
+ *     this. The language will say a well-formed program may not recurse, but
+ *     compilers are not forced to detect that recursion may happen.
+ *
+ *     CLOSED: November 29, 2002."
+ *
+ * In GLSL 1.10 the behavior of recursion is undefined.  Compilers don't have
+ * to reject shaders (at compile-time or link-time) that contain recursion.
+ * Instead they could work, or crash, or kill a kitten.
+ *
+ * From page 44 (page 50 of the PDF) of the GLSL 1.20 spec:
+ *
+ *     "Recursion is not allowed, not even statically. Static recursion is
+ *     present if the static function call graph of the program contains
+ *     cycles."
+ *
+ * This langauge clears things up a bit, but it still leaves a lot of
+ * questions unanswered.
+ *
+ *     - Is the error generated at compile-time or link-time?
+ *
+ *     - Is it an error to have a recursive function that is never statically
+ *       called by main or any function called directly or indirectly by main?
+ *       Technically speaking, such a function is not in the "static function
+ *       call graph of the program" at all.
+ *
+ * \bug
+ * If a shader has multiple cycles, this algorithm may erroneously complain
+ * about functions that aren't in any cycle, but are in the part of the call
+ * tree that connects them.  For example, if the call graph consists of a
+ * cycle between A and B, and a cycle between D and E, and B also calls C
+ * which calls D, then this algorithm will report C as a function which "has
+ * static recursion" even though it is not part of any cycle.
+ *
+ * A better algorithm for cycle detection that doesn't have this drawback can
+ * be found here:
+ *
+ * http://en.wikipedia.org/wiki/Tarjan%E2%80%99s_strongly_connected_components_algorithm

-This directory contains the source code for SGI's OpenGL Xt/Motif widgets,
-slightly modified by Jeroen van der Zijp to work better with Mesa.
-
-To compile the widget code (producing lib/libGLw.a) cd to the widgets/
-directory and type 'make <config>' where <config> is the system configuration
-you used to compile Mesa (like 'make linux').  This hasn't been tested on
-many systems so let us know if you have trouble.
-
-If you want to make a Linux ELF shared lib instead of the non-shared .a
-file see the notes in the Makefile.
-
-If you want to build with Motif support, edit Makefile.X11, looking
-for the "Motif" information.
-
-The SGI copyright is as follows.

  * \brief Get pointer offset into stencil buffer.
  *
- * The stencil buffer interleaves two rows into one. Yay for crazy hardware.
- * The table below demonstrates how the pointer arithmetic behaves for a buffer
- * with positive stride (s=stride).
- *
- *     x    | y     | byte offset
- *     --------------------------
- *     0    | 0     | 0
- *     0    | 1     | 1
- *     1    | 0     | 2
- *     1    | 1     | 3
- *     ...  | ...   | ...
- *     0    | 2     | s
- *     0    | 3     | s + 1
- *     1    | 2     | s + 2
- *     1    | 3     | s + 3
+ * The stencil buffer is W tiled. Since the GTT is incapable of W fencing, we
+ * must decode the tile's layout in software.
  *

+ * have taken this to mean either linear RGB or linear RGBA.
+ *
+ * The GL_ARB_texture_compress_rgtc spec says:
+ *
+ *    "19) Should the GL_NUM_COMPRESSED_TEXTURE_FORMATS and
+ *        GL_COMPRESSED_TEXTURE_FORMATS queries return the RGTC formats?
+ *
+ *        RESOLVED:  No.
+ *

+ *        by this query [GL_COMPRESSED_TEXTURE_FORMATS"] are those
+ *        corresponding to formats suitable for general-purpose usage.
+ *        The renderer will not enumerate formats with restrictions that
+ *        need to be specifically understood prior to use."
+ *
+ *        Compressed textures with just red or red-green components are
+ *        not general-purpose so should not be returned by these queries
+ *        because they have restrictions.
+ *
+ *        Applications that seek to use the RGTC formats should do so
+ *        by looking for this extension's name in the string returned by
+ *        glGetString(GL_EXTENSIONS) rather than
+ *        what GL_NUM_COMPRESSED_TEXTURE_FORMATS and
+ *        GL_COMPRESSED_TEXTURE_FORMATS return."
+ *
+ * There is nearly identical wording in the GL_EXT_texture_compression_rgtc
+ * spec.
+ *
+ * The GL_EXT_texture_rRGB spec says:
+ *
+ *    "22) Should the new COMPRESSED_SRGB_* formats be listed in an
+ *        implementation's GL_COMPRESSED_TEXTURE_FORMATS list?
+ *
+ *        RESOLVED:  No.  Section 3.8.1 says formats listed by
+ *        GL_COMPRESSED_TEXTURE_FORMATS are "suitable for general-purpose
+ *        usage."  The non-linear distribution of red, green, and
+ *        blue for these sRGB compressed formats makes them not really
+ *        general-purpose."
+ *
+ * The GL_EXT_texture_compression_latc spec says:
+ *
+ *    "16) Should the GL_NUM_COMPRESSED_TEXTURE_FORMATS and
+ *        GL_COMPRESSED_TEXTURE_FORMATS queries return the LATC formats?
+ *
+ *        RESOLVED:  No.
+ *
+ *        The OpenGL 2.1 specification says "The only values returned
+ *        by this query [GL_COMPRESSED_TEXTURE_FORMATS"] are those
+ *        corresponding to formats suitable for general-purpose usage.
+ *        The renderer will not enumerate formats with restrictions that
+ *        need to be specifically understood prior to use."
+ *
+ *        Historically, OpenGL implementation have advertised the RGB and
+ *        RGBA versions of the S3TC extensions compressed format tokens
+ *        through this mechanism.
+ *
+ *        The specification is not sufficiently clear about what "suitable
+ *        for general-purpose usage" means.  Historically that seems to mean
+ *        unsigned RGB or unsigned RGBA.  The DXT1 format supporting alpha
+ *        (GL_COMPRESSED_RGBA_S3TC_DXT1_EXT) is not exposed in the list (at
+ *        least for NVIDIA drivers) because the alpha is always 1.0 expect
+ *        when it is 0.0 when RGB is required to be black.  NVIDIA's even
+ *        limits itself to true linear RGB or RGBA formats, specifically
+ *        not including EXT_texture_sRGB's sRGB S3TC compressed formats.
+ *
+ *        Adding luminance and luminance-alpha texture formats (and
+ *        certainly signed versions of luminance and luminance-alpha
+ *        formats!) invites potential comptaibility problems with old
+ *        applications using this mechanism since old applications are
+ *        unlikely to expect non-RGB or non-RGBA formats to be advertised
+ *        through this mechanism.  However no specific misinteractions
+ *        with old applications is known.
+ *
+ *        Applications that seek to use the LATC formats should do so
+ *        by looking for this extension's name in the string returned by
+ *        glGetString(GL_EXTENSIONS) rather than
+ *        what GL_NUM_COMPRESSED_TEXTURE_FORMATS and
+ *        GL_COMPRESSED_TEXTURE_FORMATS return."
+ *
+ * There is no formal spec for GL_ATI_texture_compression_3dc.  Since the
+ * formats added by this extension are luminance-alpha formats, it is
+ * reasonable to expect them to follow the same rules as
+ * GL_EXT_texture_compression_latc.  At the very least, Catalyst 11.6 does not
+ * expose the 3dc formats through this mechanism.
