+
+    OpenGL 1.0 or later is required
+    This extensions is written against the OpenGL 1.4 Specification.
+
+Overview
+
+    This extension adds a new pixel storage parameter to indicate that
+    images are to be packed in top-to-bottom order instead of OpenGL's
+    conventional bottom-to-top order.  Only pixel packing can be
+    inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter,
+    etc).
+
+    Almost all known image file formats store images in top-to-bottom
+    order.  As it is, OpenGL reads images from the frame buffer in
+    bottom-to-top order.  Thus, images usually have to be inverted before
+    writing them to a file with image I/O libraries.  This extension
+    allows images to be read such that inverting isn't needed.
+
+IP Status
+
+    None
+
+Issues
+
+    1. Should we also defined UNPACK_INVERT_MESA for glDrawPixels, etc?
+
+    Resolved:  No, we're only concerned with pixel packing.  There are other
+    solutions for inverting images when using glDrawPixels (negative Y pixel
+    zoom) or glTexImage (invert the vertex T coordinates).  It would be easy
+    enough to define a complementary extension for pixel packing in the
+    future if needed.

+Overview
+
+    Since Mesa allows RGB rendering into drawables with PseudoColor,

+
+    The colormap associated with a window can be queried with normal
+    Xlib functions but there is no colormap associated with pixmaps.
+
+    The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap

+    Mesa 2.2 or later is required.
+
+Overview
+
+    Mesa is often used as a client library with no integration with
+    the computer's window system (an X server, for example).  And since
+    Mesa does not have an event loop nor window system callbacks, it
+    cannot properly respond to window system events.  In particular,
+    Mesa cannot automatically detect when a window has been resized.
+
+    Mesa's glViewport command queries the current window size and updates
+    its internal data structors accordingly.  This normally works fine
+    since most applications call glViewport in responce to window size
+    changes.
+
+    In some situations, however, the application may not call glViewport
+    when a window size changes but would still like Mesa to adjust to
+    the new window size.  This extension exports a new function to solve
+    this problem.

+
+Overview
+	
+    This extension modifies the way in which points are rendered,
+    specifically when they're textured.  When SPRITE_POINT_MESA is enabled
+    a point is rendered as if it were a quadrilateral with unique texture
+    coordinates at each vertex.  This extension effectively turns points
+    into sprites which may be rendered more easily and quickly than using
+    conventional textured quadrilaterals.
+
+    When using point size > 1 or attenuated points this extension is an
+    effective way to render many small sprite images for particle systems
+    or other effects.
+
+Issues:
+
+    1. How are the texture coordinates computed?
+
+       The lower-left corner has texture coordinate (0,0,r,q).
+       The lower-right, (1,0,r,q).  The upper-right, (1,1,r,q).
+       The upper-left, (0,1,r,q).
+
+    2. What about texgen and texture matrices?
+
+       Texgen and the texture matrix have no effect on the point's s and t
+       texture coordinates.  The r and q coordinates may have been computed
+       by texgen or the texture matrix.  Note that with a 3D texture and/or
+       texgen that the r coordinate could be used to select a slice in the
+       3D texture.
+
+    3. What about point smoothing?
+
+       When point smoothing is enabled, a triangle fan could be rendered
+       to approximate a circular point.  This could be problematic to
+       define and implement so POINT_SMOOTH is ignored when drawing sprite
+       points.
+
+       Smoothed points can be approximated by using an appropriate texture
+       images, alpha testing and blending.
+
+       POLYGON_SMOOTH does effect the rendering of the quadrilateral, however.
+
+    4. What about sprite rotation?
+
+       There is none.  Sprite points are always rendered as window-aligned
+       squares.  One could define rotated texture images if desired.  A 3D
+       texture and appropriate texture r coordinates could be used to
+       effectively specify image rotation per point.
+
+    5. What about POLYGON_MODE?
+
+       POLYGON_MODE does not effect the rasterization of the quadrilateral.
+
+    6. What about POLYGON_CULL?
+
+       TBD.  Polygon culling is normally specified and implemented in the
+       transformation stage of OpenGL.  However, some rasterization hardware
+       implements it later during triangle setup.
+
+       Polygon culling wouldn't be useful for sprite points since the
+       quadrilaterals are always defined in counter-clockwise order in
+       window space.  For that reason, polygon culling should probably be
+       ignored.
+
+    7. Should sprite points be alpha-attenuated if their size is below the
+       point parameter's threshold size?
+
+    8. Should there be an advertisized maximum sprite point size?
+
+       No.  Since we're rendering the point as a quadrilateral there's no
+       need to limit the size.

+
+    When SPRITE_POINT_MESA is enabled points are rasterized as screen-
+    aligned quadrilaterals.  If the four vertices of the quadrilateral
+    are labeled A, B, C, and D, starting at the lower-left corner and moving
+    counter-clockwise around the quadrilateral, then the vertex and
+    texture coordinates are computed as follows:
+
+      vertex   window coordinate       texture coordinate
+        A      (x-r, y-r, z, w)          (0, 0, r, q)
+        B      (x+r, y-r, z, w)          (1, 0, r, q)
+        C      (x+r, y+r, z, w)          (1, 1, r, q)
+        D      (x-r, y+r, z, w)          (0, 1, r, q)
+
+    where x, y, z, w are the point's window coordinates, r and q are the
+    point's 3rd and 4th texture coordinates  and r is half the point's
+    size.  The other vertex attributes (such as the color and fog coordinate)
+    are simply duplicated from the original point vertex.
+
+    Point size may either be specified with PointSize or computed
+    according to the EXT_point_parameters extension.
+
+    The new texture coordinates are not effected by texgen or the texture
+    matrix.  Note, however, that the texture r and q coordinates are passed
+    unchanged and may have been computed with texgen and/or the texture
+    matrix.
+
+    If multiple texture units are present the same texture coordinate is
+    used for all texture units.
+
+    The point is then rendered as if it were a quadrilateral using the
+    normal point sampling rules.  POLYGON_MODE does not effect the
+    rasterization of the quadrilateral but POLYGON_SMOOTH does.
+

+
+    glXSwapIntervalMESA specifies the minimum number of video frame periods
+    per buffer swap.  (e.g. a value of two means that the color buffers
+    will be swapped at most every other video frame.)  A return value
+    of zero indicates success; otherwise an error occurred.  The interval
+    takes effect when glXSwapBuffers is first called subsequent to the
+    glXSwapIntervalMESA call.
+
+    A video frame period is the time required by the monitor to display a 
+    full frame of video data.  In the case of an interlaced monitor,
+    this is typically the time required to display both the even and odd 
+    fields of a frame of video data.
+
+    If <interval> is set to a value of 0, buffer swaps are not synchron-
+    ized to a video frame.  The <interval> value is silently clamped to
+    the maximum implementation-dependent value supported before being
+    stored.
+
+    The swap interval is not part of the render context state.  It cannot
+    be pushed or popped.  The current swap interval for the window
+    associated with the current context can be obtained by calling
+    glXGetSwapIntervalMESA.  The default swap interval is 0.
+
+    On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
+    the swap interval to 1.
+
+Errors
+
+    glXSwapIntervalMESA returns GLX_BAD_VALUE if parameter <interval> is

+
+    Based on WGL_I3D_swap_frame_usage version 1.3.
+
+Overview
+
+    This extension allows an application to deterine what portion of the
+    swap period has elapsed since the last swap operation completed.  The
+    "usage" value is a floating point value on the range [0,max] which is
+    calculated as follows:
+
+                              td
+                   percent = ----
+                              tf
+
+    where td is the time measured from the last completed buffer swap (or
+    call to enable the statistic) to when the next buffer swap completes, tf
+    is the entire time for a frame which may be multiple screen refreshes
+    depending on the swap interval as set by the GLX_SGI_swap_control or
+    GLX_OML_sync_control extensions. 
+
+    The value, percent, indicates the amount of time spent between the
+    completion of the two swaps.  If the value is in the range [0,1], the
+    buffer swap occurred within the time period required to maintain a
+    constant frame rate.  If the value is in the range (1,max], a constant
+    frame rate was not achieved.  The value indicates the number of frames
+    required to draw.
+
+    This definition of "percent" differs slightly from
+    WGL_I3D_swap_frame_usage.  In WGL_I3D_swap_frame_usage, the measurement
+    is taken from the completion of one swap to the issuance of the next.
+    This representation may not be as useful as measuring between
+    completions, as a significant amount of time may pass between the
+    issuance of a swap and the swap actually occuring.
+
+    There is also a mechanism to determine whether a frame swap was
+    missed.

+
+    The frame usage is measured as the percentage of the swap period elapsed
+    between two buffer-swap operations being commited.  In unextened GLX the
+    swap period is the vertical refresh time.  If SGI_swap_control or
+    MESA_swap_control are supported, the swap period is the vertical refresh
+    time multiplied by the swap interval (or one if the swap interval is set
+    to zero).
+    
+    If OML_sync_control is supported, the swap period is the vertical
+    refresh time multiplied by the divisor parameter to
+    glXSwapBuffersMscOML.  The frame usage in this case is less than 1.0 if
+    the swap is commited before target_msc, and is greater than or equal to
+    1.0 otherwise.  The actual usage value is based on the divisor and is
+    never less than 0.0.
+
+       int glXBeginFrameTrackingMESA(Display *dpy,
+                                     GLXDrawable drawable,
+				     float *usage)
+
+    glXGetFrameUsageMESA returns a floating-point value in <usage>
+    that represents the current swap usage, as defined above.
+
+    Missed frame swaps can be tracked by calling the following function:
+
+       int glXBeginFrameTrackingMESA(Display *dpy,
+                                     GLXDrawable drawable)
+
+    glXBeginFrameTrackingMESA resets a "missed frame" count and
+    synchronizes with the next frame vertical sync before it returns.
+    If a swap is missed based in the rate control specified by the
+    <interval> set by glXSwapIntervalSGI or the default swap of once
+    per frame, the missed frame count is incremented.
+
+    The current missed frame count and total number of swaps since
+    the last call to glXBeginFrameTrackingMESA can be obtained by
+    callling the following function:
+
+       int glXQueryFrameTrackingMESA(Display *dpy,
+                                     GLXDrawable drawable,
+				     int64_t *swapCount,

+                                     float *lastMissedUsage)
+
+    The location pointed to by <swapCount> will be updated with the
+    number of swaps that have been commited.  This value may not match the
+    number of swaps that have been requested since swaps may be
+    queued by the implementation.  This function can be called at any
+    time and does not synchronize to vertical blank.
+
+    The location pointed to by <missedFrames> will contain the number
+    swaps that missed the specified frame.  The frame usage for the
+    last missed frame is returned in the location pointed to by
+    <lastMissedUsage>.
+
+    Frame tracking is disabled by calling the function
+
+       int glXEndFrameTrackingMESA(Display *dpy,
+                                   GLXDrawable drawable)
+
+    This function will not return until all swaps have occurred.  The
+    application can call glXQueryFrameTrackingMESA for a final swap and
+    missed frame count.
+
+    If these functions are succesful, zero is returned.  If the context
+    associated with dpy and drawable is not a direct context,
+    GLX_BAD_CONTEXT is returned.
+

+

+
+Overview
+
+    In order to set the current raster position to a specific window
+    coordinate with the RasterPos command, the modelview matrix, projection
+    matrix and viewport must be set very carefully.  Furthermore, if the
+    desired window coordinate is outside of the window's bounds one must
+    rely on a subtle side-effect of the Bitmap command in order to circumvent
+    frustum clipping.
+
+    This extension provides a set of functions to directly set the
+    current raster position, bypassing the modelview matrix, the
+    projection matrix and the viewport to window mapping.  Furthermore,
+    clip testing is not performed.
+
+    This greatly simplifies the process of setting the current raster
+    position to a specific window coordinate prior to calling DrawPixels,
+    CopyPixels or Bitmap.

+
+Overview
+
+    This extension supports texture images stored in the YCbCr format.
+    There is no support for converting YCbCr images to RGB or vice versa
+    during pixel transfer.  The texture's YCbCr colors are converted to
+    RGB during texture sampling, after-which, all the usual per-fragment
+    operations take place.  Only 2D texture images are supported (not
+    glDrawPixels, glReadPixels, etc).
+
+    A YCbCr pixel (texel) is a 16-bit unsigned short with two components.
+    The first component is luminance (Y).  For pixels in even-numbered
+    image columns, the second component is Cb.  For pixels in odd-numbered
+    image columns, the second component is Cr.  If one were to convert the
+    data to RGB one would need to examine two pixels from columns N and N+1
+    (where N is even) to deduce the RGB color.

+    exceptions:
+
+    * The value of internalformat and format can not be YCBCR_MESA.
+
+
+    In section 3.8.2, Alternate Texture Image Specification Commands, on
+    page 129, insert this paragraph after the first full paragraph on the
+    page:
+
+         "If the internal storage format of the image being updated by
+    TexSubImage2D is YCBCR_MESA then format must be YCBCR_MESA.

+Errors
+
+    INVALID_ENUM is generated by TexImage2D if <internalFormat> is
+    MESA_YCBCR but <format> is not MESA_YCBCR.
+
+    INVALID_ENUM is generated by TexImage2D if <format> is MESA_YCBCR but
+    <internalFormat> is not MESA_YCBCR.
+
+    INVALID_VALUE is generated by TexImage2D if <format> is MESA_YCBCR and
+    <internalFormat> is MESA_YCBCR and <border> is not zero.
+
+    INVALID_OPERATION is generated by TexSubImage2D if the internal image
+    format is YCBCR_MESA and <format> is not YCBCR_MESA.
+
+    INVALID_OPERATION is generated by CopyTexSubImage2D if the internal
+    image is YCBCR_MESA.
+    
+New State
+
+    Edit table 6.16 on page 231: change the type of TEXTURE_INTERNAL_FORMAT
+    from n x Z42 to n x Z43 to indicate that internal format may also be
+    YCBCR_MESA.
