-
-
-
-Introduction
-------------
-
-Mesa uses an even/odd version number scheme like the Linux kernel.
-Odd numbered versions (such as 6.5) designate new developmental releases.
-Even numbered versions (such as 6.4) designate stable releases.
-
-
-
-New Features
-------------
-
-GL_EXT_timer_query  - used to get elapsed time information from the renderer.
-
-
-
-Driver Interface Changes
-------------------------
-
-Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
-the two-sided versions: Driver.Stencil*Separate().
-
-
-
-To Do
------
-Fix linux-glide target/driver.
-Fix lambda calculation for frag progs.
-
-
-
-
-Removed Extensions
-------------------
-
-The following extensions have been removed:
-
-  GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query.
-
-
-
-To Do (someday) items
----------------------
- Switch to freeglut
- Increase MAX_DRAWBUFFERS
-
-
-
-
-Driver			Status
-----------------------	----------------------
-DRI drivers		varies with the driver
-XMesa (Xlib)		implements OpenGL 1.5
-OSMesa (off-screen)	implements OpenGL 1.5
-Glide (3dfx Voodoo1/2)	implements OpenGL 1.3
-SVGA			implements OpenGL 1.3
-Wind River UGL		implements OpenGL 1.3
-Windows/Win32		implements OpenGL 1.5
-DJGPP			implements OpenGL 1.5
-GGI			implements OpenGL 1.3
-BeOS			implements OpenGL 1.5
-Allegro			needs updating
-D3D			needs updating

+/*
+ * How this works:
+ * 1. We load the image into a 2D texture.
+ * 2. We generate a sequence of RGB images in which the R component
+ *    is really the S texture coordinate and the G component is really
+ *    the T texture coordinate.
+ *    By warping the mapping from R to S and G to T we can get non-linear
+ *    distortions.
+ * 3. Draw the warped image (a 2-D warping function) with pixel texgen
+ *    enabled.
+ * 4. Loop over the warped images to animate.
+ *
+ * The pixel texgen extension can also be used to do color-space
+ * conversions.  For example, we could convert YCR to RGB with a
+ * 3D texture map which takes YCR as the S,T,R texture coordinate and
+ * returns RGB texel values.
+ *
+ * You can use this extension in (at least) two ways:
+ * 1. glDrawPixels w/ color space conversion/warping
+ * 2. glDrawPixels to spatially warp another image in texture memory
+ *
+ * We're basically using glDrawPixels to draw a texture coordinate image.
